Video: Tips & Tricks: Large Assembly Simulation | Duration: 5012s | Summary: Tips & Tricks: Large Assembly Simulation

Transcript for "Tips & Tricks: Large Assembly Simulation": I'm just leaving it on for now. That works. Alright. Welcome. Welcome, everybody. We'll get started here in about another minute or so with some introductions, but, happy Thursday. And, what did they say? So it's hump day Wednesday. Thirsty Thursdays, I guess, is the thing. Taco Tuesday, right, the whole deal. So welcome, everybody. Hey. How are you doing, Nick? Good. How about yourself? Pretty good, man. So I'd be ready for, yeah, getting ready for spooky season. Mhmm. Yep. Let me turn on my chat here. And, so there's q and a here, and then there's chat, ladies and gentlemen. Those of you that are coming in, feel free. This is gonna be kind of an open session. We're just talking about all things. And so, yeah, if you have questions along the way, we're happy to help answer as best we can. And, we do have some questions lined up that we've gotten over the past month or so. But, but, yeah, let's go ahead and get started, I guess. We have a good group here coming in. I will start off with introductions. And so, again, welcome to the SOLIDWORKS Symposium, a place where we talk about all things simulation, but mostly SOLIDWORKS Simulation where all simulation is treated equal. We don't discriminate. If we know it, then we'll we'll talk about it. So, my name is Enrique Garcia, the, what's, what's my call sign now? The self proclaimed simulation sensei and senior simulation specialist here at GoEngineer. Man, say that 5 times. And I'm here accompanied by, my bug good buddy, the the legend the myth legend, the quantifier of quantitative results himself, senior simulation specialist Nick Pessiteri. How are you doing, man? Good. How about you? Doing pretty good. Everybody. This is Nick. I know we're gonna eventually show her. So, hey, at the bottom of the screen, can you hide that thing? Just curious see. Where it says Yeah. Oh, yeah. Yeah. Let's get rid of that. Good good call there. Good catch. Kinda pops up there. But, yeah, that's, that's the intro here. So, again, this is more of a radio style radio show style podcast. We are gonna be focusing on simulation, large assemblies, tips and tricks here as our main showcase. We are gonna continue on with, kind of a similar format from our first episode. This is episode number 2, Nick. So, yeah, we're doing pretty good. Maybe we'll get syndicated in a couple of years. Looks good, man. Let me introduce myself, just just quickly. Like I mentioned earlier, I'm with the senior I would have I'm I'm one of the senior application engineers here at Goengineer based out of the Arizona office. And, yeah, I just, I specialize in SOLIDWORKS simulation and a little bit of abacus. Playing around with that tool and the 3 d experience platform as well. We're we're all, we're all perpetual students here at Goengineer, so we're learning and learning and learning. But as far as some other things, I procured a a couple of us of couple of a number of certifications over the years. I enjoy helping out with the community with the the SOLIDWORKS user group here. I present some simulation topics from time to time. But, yeah, I just gravitate towards teaching and and collaborating with, with students, people that wanna learn. So I'm a I'm a teacher first, I think, and a presenter, and I I definitely enjoy that a lot. And I like to help out with, as best I can with, with, yeah, with people and and, again, support. I like to support educational programs. I was a a band woodwind instructor for over 10 years, not too long ago over here in Valley. Wow. Wow. Taught, yeah. Yeah. I taught at a couple of high schools, woodwind clinics, band camps, marching clinics. You name it, man. It's been a lot of fun. So so, yeah, it's kinda part of my deal. Yeah. We know Enrique's, Achilles' heel. He does not like, music. Right? That's right. Don't bring up music. He can't stand it. I'm just right. Don't play out of tune. That's that's a that's a pet peeve of mine, man. Yes. Don't sing out of tune. Don't don't don't play out of tune. But, but I'm also a tinkerer, and, I'm a foodie, so I like taking things apart. 3 d printing has been a fun gig, just playing around with that. And, yeah, who doesn't like tacos, right, and food? So Mhmm. There I am, man. A little bit about yourself, Nick. Go ahead and tell us about yourself there. Yeah. So, again, yeah, hello, everyone. My name is Nick Wazaderi. My title here at, I guess you could say, EdgoEngineer is a senior specialist in simulation. And as you can see on the slide here, I reside out of the Saint Louis, Missouri location. I've worked in, as you can see on the screen, I've worked in the, power recycling and mining in industries as an engineer, so that's my work background. And, some some things I like to do outside of work is or a a lot not a known thing by people is, actually, I was actually a mechanic for 12 years, and then I went to school for engineering, and lo and behold, here I am now. But, yeah, I was a mechanic in a past career. I do like to do weight training, to keep of course, to stay healthy. And, I like to shoot compound bow mainly for target shooting, but, not much fun for but that's a little bit about me. Go ahead. Yeah. Maybe you'll give give give give me a lesson one day, man. Yep. Very cool. Let me make sure the chat is open here. My screen keeps popping off there. Make sure I have that handy. Alright. Yeah. Thank you for that, Nick. Let's let's keep it going here. So, just quickly quick slide, just a a quick overview of simulation capabilities. We're gonna be focusing on the SOLIDWORKS portfolio here with SOLIDWORKS Simulation. There's 3 basic types of simulation tools that are built into the SOLIDWORKS ecosystem. We have SOLIDWORKS Simulation, which is FEA, SOLIDWORKS Plastics, which is our plastic thermal injection molding simulator, and then we have SOLIDWORKS Flow Simulation that handles heat transfer and fluid dynamics. So there's there's that. If you have any questions, please let us know. Alright. Here is the agenda for us today. We're gonna be starting off with some GoEngineer news as usual for our program, then we're gonna jump into customer simulation questions. These are questions that Nick and I have gotten over the past couple weeks from customers, prospects, conversations from just people in the community, and, we'll we'll showcase, the large assembly simulation tips and tricks. We got a good 5 or 6 of them to show you to help some some tricks and tips that can help you with working with larger assemblies. So we wanna share those these tools with you just because they are pretty helpful, and that's it. So that's the show for us today. Let's start off with some Goengineer news. So this was pretty good for, for a limited time. Go engineer is, selling a license of SOLIDWORKS premium. This is pretty good, everybody, and that will come with a full license of simulation professional. So, so, yeah, that's, that's one of the best deals I've seen in a few years, to be honest. Yep. Yeah. Pretty excited about this one. Yeah. Simpro, as you know, Nick, it's my favorite package to promote. It just it just gives you the best bang for your buck, man. Yeah. You can do it. You definitely do a lot more, beyond just pure FEA with Sympro, like, you know, what what thermal analysis, optimization studies. You know, those are big ones that people like to use it with. And by the way, you can make your screen bigger for those online. Yeah. We're looking at the chat here, and someone, is everyone able able to see the screen okay? I think we have one person here. I'm hoping they're having some trouble. They got it worked up. But if you wanna see it full screen, just left click Oh, perfect. Click on the screen, and then there should be a, up at the bottom right corner, a full screen icon that makes the image bigger if you want. Yeah. Absolutely. So you don't you don't have the little little border you have there? Border. Yeah. Yeah. Yeah. Very good. Thanks for that feedback, everybody. It's good to know we're doing good here. But, yeah, it's a it's it's a pretty I I I'll, going back to that SIM SIM Pro package that comes with SIM Premium. It's it's, yeah, that that's a that's awesome. I like to promote that SIM Pro package. Right? It just it gives you a lot of stuff. Right? It gives you a thermal in addition in addition to just structural, gives you thermal frequency optimization and even some dynamic capabilities for that drop test. So again, that's just for the price of premium. That's that's an amazing deal, man. So Yep. So, yes, spread the word, everybody. It's, also, just a quick note. I did I I did talk to a sales guy, about this to get some details and maybe getting gotchas. They they said that the deal is for perpetual seats only, so so no term licensing. So but, yeah, if you're in the market for a, you know, permanent seat of SolidWorks and, you know, just another seat of you get simulation. So if you're in the market for both, that's a good deal there. So it's it's a good time to be a SIM customer, I think. It's q 4. Right? There's, yeah, it's it's time to do some early simulation Christmas shopping. So Yeah. So give that a shot. Also, they they said that they're expecting to have, this promotion for the month of November, for sure, and then some sort of promotion for all FEA and flow simulation licenses. So it is for sure for November. Not sure about December, but, yeah, it might extend. But we we that's not for certain as far as I know. But, but definitely take advantage. Talk to your sales guy if you're even interested in it. It's a good time for sure. So especially if they're in the market for a license. Yeah. That's that's all I have to say about that. Yeah. Just as as we get closer, right, to, the holidays, which is why it's good to get this over with. As we're getting close to Turkey Day, everyone's traveling. It's time to get, yeah, get some pie and turkey and watch some football. Right, Nick? Oh, yeah. Oh, yeah. But, yeah, good good deals, man. I just I just I'm kind of still still in shock. I I I've been doing this for over 15 years now, and I haven't seen this much amount of attention to simulation products in a good 6, 7 years. It's, it's kinda nice. Yep. So, but, yeah, that's that's the biggest news I have. The other one, speaking of attention to simulation products, I wanted to share something really quick here. If you visit the Goengineer homepage at goengineer.com, you're gonna see a pretty big showcase or promotion for our simulation products there, probably thanks to all the the promotions we're getting directly from SolidWorks and, Dassault. We're we're calling it the 5 steps of SIM driven design. And if you click on the start today for free button there, it's gonna break down how to start with our free simulation products, Simulation Express, which comes with all seats of SOLIDWORKS, by the way. So you have it now if you don't have simulation, and also how or when you could potentially graduate to the next level of simulation depending on what kind of analysis work you may wanna perform. This is geared basically to show, maybe your decision makers at your companies so that, you can start a conversation with them without getting too into the weeds and technical, basically. And there's also some links here that, to some some and actually pretty nicely written article, and there's an ebook, which I when I checked it out, it's more of a longer brochure. I think it was done up for with from Dassault, I think, directly, but you can download it to help with your maybe ROI positioning. And, you know, there's a case study or 2 in there for sure for, from real world companies that, have become more efficient with simulation in SOLIDWORKS. And, again, just just giving you some ammunition, basically, if you if you wanna get if you get some pushback or or if you're wanting to just casually start that conversation with your leadership, maybe he just send them a random chat with the with that brochure, kinda like those weird random TikToks you get from your buddy, right, for kicks and, for fun. Just, yeah, see see if they respond back or something. So, kinda, yeah, just kinda something. It's a good kind of in in in an initiation type of thing. So, yeah, just something that we've started to promote there. Here, last, last piece of, news. I just wanted to highlight some upcoming webinars in a simulation webinar that you can attend online next month. The 1st year starts with the 1st week of November, on November 6th. This is gonna be the 1st SolidWorks, what's new series of sessions, where we cover the the new functionality of SolidWorks for 2025. There'll be a a simulation section in there for sure on one of these sessions, so so keep an eye out for that. Also, Nick, you were saying that you you did they did a little bit of work on this as well. Right? Yeah. So the the what's new of simulation is something I did. It's not my voice, but, it is all of the what's new of simulation is all of our Yep. That's my time. Yeah. Kudos, man. It's a it's a lot of work. We've we've all had to do some of these in the past. So Yeah. Yeah. Thank you for your for your effort, man. But, yeah, that's good. So and one one more thing here, the other webinar here, if you're if you've ever been interested in learning more about dynamic shock analysis or impact testing in particular, 2 of our very own engineers, Sean Bentley and Taryn Packer, will be presenting on this topic on November 20th here for GoEngineering. It's kinda same similar format, a webinar style. Definitely recommend you go and check it out. There'll be a little bit more there'll be a little bit for for new users and seasoned simulation users in there, which which is true for all of these beginning to end series of presentation that we've been pushing out, just over the various topics. I did one last week on bolts with simulation, and and, Nick, you also did one a few weeks ago, right, on buckling? Yeah. Yeah. From, SolidWorks from from beginning to end, buckling analysis. Yep. It's out there. They're pretty, pretty yeah. They're pretty in-depth. They're they're pretty nice, really technical. We start with hand calculations and how you can go from a hand calc into SolidWorks and then how we can do that particular functionality throughout the product so you can see the the huge, just a breadth of what you can do with these tools. So you're not always just kind of starting off and doing hand calcs. Hand calcs are great. Right? They're good for spot checking. But when it comes to doing 3 d hand calcs, that's Yeah. That's Good luck at that. That's painful. So Yeah. Probably preaching to the fly on that. Is that a Jenga Jenga set that's getting in there? I think so. Yeah. Yeah. Maybe it got looks like it got pummeled by a ball or something. Yeah. Yeah. I think that's an animation that we show in that, that Yeah. That particular presentation at Jenga set. Yeah. Pretty enticing. I'm gonna check that out. So but, yeah, those are the the that's the Go engineer simulation news we have for you for this round. So let let's go into the next section here. As as this is, yeah, the next section. Let's go through some simulation questions next. Then, again, we'll jump into the main showcase topic and cover some large assembly simulation tips and tricks for you. Alright. Well Alright. I'll kinda start it off here for you. So one of the questions that we get is, as you can see on the screen, is why is, is manually made local contact or what it used to be called contact set the more preferred contact over, component contact? Now this is something that's not really known by people. You know, I see people a lot of times when they first start using simulation, they'll they'll gravitate toward more using component contact, and, it it tends to or if I kinda lean into more of the answer here, but there's a, as you can see on the screen here, there's a, a link well, you probably can't do anything with it, but, there's a a a blog that was done in the past called component contact or contact set. Which one makes sense for you? If you start if you do a Google search for that, it's a blog that, we actually did back then. It's under the c it it's it's still under CATI's website. I mean, we're all GoEngineer now, by the way. But, it's a blog that we did, that is, it kinda shocked me what I learned from just that blog, being as even with, simulation ae. So so the cliff notes, to this answer to this question is, is, component contacts are just like their name implies, contact between components. These contacts are easy to set up using component contact but have a downside. So when the solver generates the contact, every node on one component is checked against the nodes on the other to see if they will come into contact, satisfying the contact condition. So because it does this, this takes, time for the solver to compute or more time to compute. So, for example, on the screen here, the set of pliers is each half, was each half was selected. Go back one real quick. Oh, sure. So as you can see on the left hand side, those left and right hand side of the pliers that's meshed here, the nodes circled will never touch. But this is what's interesting about component contact is it's it's still calculated as though they might. That's what blew me away is like, woah. I did not know that component contact does that. Yeah. It's one of the biggest gotchas. Right? It and then your calculation time goes through the roof. Yep. Absolutely. Just go ahead and click next. But so Sure. So, again, component contacts are, again, easy to set up but lead to additional solver time. So we we always recommend using local interactions or, again, what they used to be called, contact sets depending on the year of SOLIDWORKS simulation you're using. Whenever possible, use local interactions. So local interactions utilize faces, edges, or vertices on different components to define the contact. So local inter local interactions may take a little more time to set up and, of course, may require an exploded view to make the selection easier, but the calculation time is reduced significantly using, local contacts versus component contact. Yeah. Definitely a best practice. Mhmm. Any questions on that? Let me just double check here and bring up the q and a or the chat. Feel free to use either one here, ladies and gentlemen. Looks good. Let's keep keep on going here. So I have one for you as well. So thank you for that, Nick. So here's my first question. This, this one is one of our, this is more geared for some of our newer simulation users. I thought I'd answer this question. It comes up a lot, every time I teach, simulation introductory course. Looks like there's a question here from, Michael here. Well, where do you find more info on buckling analysis mentioned earlier? So, yeah, good question. Yeah. I definitely would, look out. I think we have that buckling beginning to end. Is that coming out soon, Nick? I think it's out. Yeah. It's already out there. Okay. Right on. Yeah. So definitely check out that. That's a good place to start for more content for buckling analysis. It's on our GoEngineer YouTube channel. It's, it's, the it's one of the beginning to end series. Just type in buckling beginning to end, and that should be a good a good point of, initial point there for you. Also, the simulation tutorials, if you needed just a workflow for buckling analysis, it is very similar to a, the the linear buckling anyway. It's very similar to a static study for the workflow, but there's a, there's a tutorial you can go in and follow through if you go to the help menu under SOLIDWORKS. And then there's the simulation category for simulation help. There's a little section for tutorials there. So, hopefully, that'll get you started there, Michael. Let's continue here. Let's talk a little bit about this, this, this question I get asked here. So, so anytime so the the question basically is, once we have a a cut plot, an iso plot, etcetera, how do we turn off these modifiers? So so you can go in and section the model and just isolate different portions of it. So anytime you have one of these qualitative plots, there seems to be no, no easy way or or intuitive way to turn them back off. Right? When I was learning simulation for the first time, I would have to either delete the plot or just leave it and then make a new plot to get all of the content, the whole volume. It was really annoying. I thought there was a bug, right, that was missing the off button. But, it it turns out that, the way that you get your plot back, to its original just an unmodified form is to go back and edit the you added, to just to the plot, just such as in this case, an ISO plot maybe, in the property manager. At the in the very last section of the panel, you're gonna see a multicolored icon. That's the on off button that you can click. Just click on that icon, and it'll turn off the modifier to revert it back to its original or former state. Definitely wish this this was changed. Right? It's, it's kinda dug in there. It's not very apparent when you first look at the interface, but it is consistent with all the modifiers. So it's in the under section of you, etcetera, all these things. But just look for that multicolored icon. I definitely wish it was in the right click menu after it was activated. I think that's something I would I think I've asked for in the past or or someone's put in, I think. But, yeah, just a just a little little heads up for everybody. So that's my first kind of tip or or question I've I've got asked recently. So I thought I'd showcase that. Yeah. You got well, you got one for us here, Nick? So this is one that does come in or gets asked often during a training is, well, what what what's the advantage of using sheet metal methods to design parts when eventually, doing an FEA analysis? Go ahead and, so the, click next. But the, so, sheet metal parts that you, you know so so when you're designing your parts using the sheet metal method, will automatically come in as shell elements for you when using, when you're setting up your analysis to run. And to expand more on this, next here. So so if I if I make a sheet metal part without the use of sheet metal methods in SolidWorks, then you have 2 other roads to take here. So as you can see on the screen here go back one real quick. That that go back real quick. That was you'll you if you're using sheet metal methods, then you're gonna have those sheet metal icons in your study your feature tree, and then, that will, of course, propagate into the study to convert that to shell elements automatically for you. Go ahead and click next here. So, so the 2 other roads to take, of course, is one being using the midsurface tool to create a midsurface on your part ahead of time. So that's something you'll have to do ahead of time if you did not use sheet metal methods. So the midsurface will then be turned into a shell element in SolidWorks sim. Go ahead and click next here. The other option is to choose, from is after you create a new SIM study. So this is actually bringing it into the, you know again, you're not using sheet metal methods. You're just going to create a study. Once it's the study, the study tree shows on the left hand side, you would right click on the component in the study tree and choose define shells fit by selected faces. So this is the other road you can take. So the one being, using the mid surface tool to make a mid surface in the geometry to be used to be turned into a shell element. And the other option is is, just create the study, right click on the component, and choose to define define shell by selected faces. Go ahead and click next here. So the so when so when you use, this method of using sheet metal to create your parts, then then here it shows how it automatically defines the shell definition for you. So it automatically defines the type, the thickness, and the offset, which is, in this case, the only one you can choose from is the, midsurface. So that this is using the sheet metal methods. It does the shell definition for you. And the only option you have for the offset is the midsurface. While if you use define shell by selected faces go back you can go ahead. While if you, use shell by selected faces or midsurface method, then you have to manually set the shell definition of the component. So as you can see, you'll have to properly choose the type, enter the thickness of the part, and also choose the offset type. So it doesn't automatically do it for you if you don't use sheet metal methods. Go ahead and click next here. So the, so if you're not sure what type to choose from, then, there's a blog, you can reference, and I actually I can actually put this in the chat here. Let me do that real quick. Yeah. No worries. The this blog is something I did a while back. I'll actually I there are actually 2 of them I wanna do. I'm gonna do, this is the one for, thick versus thin, what to choose. I'll put this in the actual chat. And then this is another one I'll send in the chat on, which was on the contact, question I had. I'll just send that in the chat too. But No. That'd be great. There's some good best practices with that thin versus thick. So, it could make a difference. Absolutely. So that's a good one to reference of, you know, how to determine when to use thin versus thick. It's in that blog. Go ahead and click forward here. Yeah. So we're using Sheema. Okay. So that's, probably where are we in this here? I'm trying to find my way. Click again. Yeah. We kinda sidetracked you trying to get you all the, that link there. Yeah. Yeah. So so, basically, what you're seeing here is what how it converts the actual I tell you what. Go back one. So the so if you're using sheet metal methods, this is actually what the shell element will look like. Right? Now if you go forward one here real quick, go ahead and click next here. So while if you're using, midsurface method, this is what the shell element will look like. Now something to be careful about here is the fact that if you're using the midsurface method, you're going to have to right click on the, other component in the study tree and exclude it from the analysis. So you don't want to mistakenly choose the actual geometry of the of the actual sheet metal part itself to define your boundary conditions to, meaning, like, your loads and your fixtures, you only wanna apply it to the shell elements. So so using the midsurface method, you're gonna have to exclude that body of the actual part out from being used in the study. Go ahead and click next here. While using the defined shell by selected faces, it pretty much does it you know, using shell by selected faces, it it does a a little bit more for you, but this is what the shell element will look like, and that's what the study tree will look like. And, of course, go ahead and click next here. The the, oh, the results you would look at for the shell element is what? Well, your typical one you're gonna get is the top. So if you if you remember, if you're using shell elements, you're gonna look at a top, and then and as you can see on the screen, there's the top of the actual shell element stress, and then let's go to the next one. There's the bottom stress of the shell element. And depending on the actual geometry and your application of stress being applied, you'll have to look at other things like go ahead and click next here, which is the, membrane stress and bending stress. So those are ones that people commonly forget when they're using shell elements, to look at, not only the top one, but to look at the bottom stress and membrane and bending if needed. So don't forget about that with the shell elements and post processing the results. And then go on to the next thing here, which is, of course, the infamous displacement plot. Right? So you can still, even with shell elements, see a displacement plot. And I think that was it on yeah. Yeah. Yeah. Thank you for that, Nick. Yeah. It's good to have those links as well. It's some good best practices in there, ladies and gentlemen, so so check them out. For my second question on my end, I'll stick to another just post processor question. I used to get asked this a lot, when I used to field tech support questions back in the day as well. Question is, is there a way to display result callouts on certain areas of my result plots and simulation? And, Yeah. Of course. Yeah. There's a few ways actually depending on what you wanna do. The first way that comes to mind is to display the maximum or minimum callouts. Some of you may already know how to do this already. It's basically edit the chart options of the the active plot. Just and then click on the the check mark for show min annotation or show max annotation, and you'll get those result callouts to appear in the graphics area, lickety split. So there's that's one way. If you're wanting specific callouts to appear at specific points in your result field, just need to use the probe tool that we have for all of all of our, qualitative plots. We can do a probe. Once in the probe property manager, just click on any area of interest there, and the nearest calculation node from that result field will be harvested, and then called out on the screen for you like you see on the on the on the slide there. You can add all the callouts you need. You can take a screenshot of that and save it to your report. A lot of us like to make PowerPoint presentations to show to our clients, so that can be a nice and quick way of doing that. If you want something more specific or or more exact because when you use the probe tool, it collects the nearest calculation node. But if you want a very specific point in, or location, you may need to first create a workflow sensitive sensor back on the SOLIDWORKS design tree. You can use these settings here on the current slide, and you may also need to go in and create a vertex in the area. You can see here I've split the surface. You can use surfacing tools or the split line tool specifically to generate a vertex, something that's selectable that makes a hard edge or corner somewhere so we can select a vertex. But, but, yeah, after that, after you've made a workflow sensitive sensor from that vertex, you may need to rerun the the the calculation again so that those points that were created, can be, something that's part of the calculation. Then you'll enter the probe tool again. Select now the from sensors radio button. And then down below, under the results section, just hit the the menu pull down outlined here under in red, and then select the name of the sensor. In this case, I chose the the sensor for the aluminum component there for this. The selection will again populate the box with the points that you preselected earlier from the creation of the sensor. And if you want the callouts to still be present after you use the probe tool, because it'll turn off. Right? So if you want it to still be on, click on that options box that reads save annotations for plot attached sensor, and I've outlined that here in the slide there in green for you. Also, if you change your mind about the permanent callouts, you can just go back into the probe tool and reselect that sensor and toggle on and off that check mark, and those callouts will disappear. I've never liked that, Nick. It's it's kinda funny how that, how that works, but that's I found that's the best way to turn off those darn those those darn callouts after the fact. Have you have you played with that recently? It's kind of a random thing. It's kinda funny you say that because I'm now I'm thinking I've never tried it myself, and maybe somebody out there can test it with maybe your screen with something open already is the little heads up toolbar at the you know, toward the center top center of your of your GUI interface, there's a little eyeball symbol. I wonder if that actually hides that annotation. Yeah. Yeah. I got that there. That's a yeah. That's it's that translucent toolbar. Right? Yeah. That's a good idea. Yeah. If you click on the eyeball, does it hide that those those annotation notes? Yeah. If anyone, if anyone has Solrick's SIM open, yes, let us know in the chat if you want. But, yeah, that's that's a good that's a good tip. I may have to check that after the webinar today. Mhmm. Yeah. What do you have, what do you have for us here, Nick? Yeah. This is a good one. I I so so for SOLIDWORKS SIM Premium Dynamics, what types of analysis can be done, and which ones are in the time domain and which ones are in the frequency domain? Well, the answer to that is, of course go ahead and click next here. Is the first one that we can do is, of course, the modal time history dynamic study. 2nd would be harmonic, 3rd being random vibration studies, 4th being response spectrum, and the final one being nonlinear dynamic. So with respect to each one, or should I say with respect to which are in the time or which are in the frequency domain, go ahead and click next here, I like to show this little chart which makes it easier to understand which are in the time versus which are in the frequencies domain. So, for example, if you look at modal time history, under the domain column, it is in, of course, the time domain. Hence, the name modal time history. Right? While if you look at harmonic random vibration and response spectrum, all of those are in the frequency domain. And the one that's not used a lot, is the nonlinear dynamic one, which actually, of course, switches to a nonlinear method of solving a dynamic problem also, used it is in the time domain. So, again, I always kinda say to, you know, people take a screenshot of this one because this really kinda clears the smoke of the load types that are used for the type of study, what domain it's in, and what outputs you get from it. Yeah. This is pretty sweet, man. I usually I have a little cheat sheet that I use when I when I teach to kinda refresh my memory and I talk about it. But, yeah, I'll I'll I'll try to grab a screenshot after this as well. It's pretty good. And that's it. Yeah. Well, let's, let's move on here. Alright. I have one more here. One more, just question. I I got this asked again recently, which is why I decided to put it in the the webinar presentation. And the question reads, what exactly is large displacement option? Why shouldn't I always turn it on? So this is, another great question. Right? Yep. I got it asked recently, but, you know, this is something I got asked in tech support back in the day at least once a week, man. It can come up a lot. And and we cover this in great detail in our simulation introductory course as well as in our advanced nonlinear course just because we we need to know the limits between static and nonlinear static, to move forward there. But, for for the novice or part time user, if you would see this option, it seems pretty innocent enough, right, just to click it, move on with your life, and, and then just your calculation all of a sudden takes a long time to run. Right? It's something that maybe took a couple of minutes, takes 30 minutes now to run. And so so yeah. So then at that point, you're like, well, damn. What what what does this option do, and what do what, yeah, what do I need to know about it? So why is it taking so much time in my simulation studies? And so the the large problem or the large displacement message here is usually meant to to be used when when when you run into this particular error message in simulation. So the one on the screen here. Yeah. So I'm kinda curious. Let me know out there. How often are you guys seeing the success of displacement using the linear method linear static method? Kinda curious. Let me know. Yeah. Probably every day. Right? Once a day. This it it usually happens when you apply large external loads, right, to to your model, which causes, you know, a larger displacement response than the what's that static solver can calculate for accurately, basically. So there's an internal ratio there that it it projects, and then if it see if it see that it's projecting, a a displacement that's way too large, then then, yeah, it's, yeah, I I've seen that a lot myself. I use the tool a lot. So, yeah, I'm just curious to see if anyone has, the idea of war stories on that for sure. Mhmm. But, but this usually also goes, it goes along with the the fact that, the response means that the the material is going past the the response to material, basically, is going past the yield strength of of, you know, the most common materials anyway, such as metals, for example. Basically, it's going past the yield strength of that traditional stress strain curve you see on the screen. So if we get this message, we can solve for a large displacement response with some careful considerations and and, with a special large displacement option. So so here's here's how it works here, ladies and gentlemen. So when running a study with a large displacement, turned off, which is by default, we assume that the geometry is relatively similar at the beginning of the calculation and at the end of the calculation. Right? So something that's an elastic deformation, something with small displacement. That's the idea. So the the model has been loaded and stresses have developed, and they've they've been calculated throughout the model as well as, again, a small degree of displacement throughout the model. So when you calculate a static study, in general, the the the the model's response will be dependent on calculating the stiffness of the material and and the geometry due to the loading event, and the responses, the model are gonna be calculated with one single calculation step. That's the idea. That's the assumption. We're calculating this from no loaded in in a in a unloaded stage to a fully loaded stage, and we're calculating this in one step. And because we're dealing with that elastic region of the stress strain curve, the the, the stiffness is relatively the same. So that's the idea. Now that's the that's the that's the key behavior. Right? So, again, this is by default in a static study. It's calculating the stiffness only once. And so if you're if you're expecting a larger displacement and, like, for the for something else, another application, then the stiffness of the model response, really would be maybe constantly changing. Right? If you take a paper clip, right, Nick, and you bend that sucker and then you you feel it give a little bit, Right? That that stiffness is now not the same as when you just kind of torque on it a little bit. So at that point, that is what the large displacement option is for. And at that point, it's gonna calculate multiple steps in the in the model, basically smaller mini static studies, if you will, just to be able to calculate the stiffness multiple times. And that's gonna give you a little more accuracy. And so that's, that's what it's gonna do, and it's gonna wanna do that until from from unloaded to fully loaded, to, again, just to capture a little more accuracy in in the response. If you look at the slide here, we can see that the the large displacement checkbox with it being off. We get a a bit of an overbite to the response. What and, again, that's just because the model is calculating the stiffness only once, and, hence, the model is probably a little bit more stiff. So a lot of the material is going over the bend, right, causing that overbite response you see there on the screen, where it says the response on the right hand side with the large displacement check mark being on. You can see a good amount of that of improvement, you know, on the on the response, basically. There's still a little bit of an overbite there, but but not as much as the previous study. And then, again, that's because of the multiple stiffness calculations that we're we're building in with that checkbox, and that's why it takes so much longer to calculate a large displacement option with the with that option turned on, basically. So, yeah, that's the that's the the crux of it. That's the main idea behind it. Now there are gonna be some limits to the accuracy of this checkbox, especially the further you you get from the the yield strength of the model in that region. The more displacements that you have, the more complex nonlinear the responses of the geometry, then, you may find that you're not gonna be able to get to the end of the calculation no matter how long it takes to run even with the large displacement option turned on. If that's the case, then your model just may need to be running a full nonlinear analysis study, which we have you covered with the sim premium for that. It is a different tier of simulation you need to get access to. But but then, yeah, we can perform some more granular operations on getting the convergence of each intermediary calculation or substep that I was talking about. It does calculate the the stiffness, but there's different strategies that can be employed there for that and, step sizes and things. And we also introduced full material, geometry and contact nonlinearity strategies in that tool. So so this this helps a little bit, but, again, if you're only flirting with the yield strength area in the in the response, it's probably okay. Just just, you know, just document a lot what you're what's really happening. It's really just change in calculation of stiffness is what you're getting with this checkbox. Yeah. And to go further with it real quick here, it this this static analysis large displacement solver is not using Newton Raphson's method, which is what the nonlinear simpremium, large displacement solver uses. So it's using something specific something unique that SOLIDWORKS developed, on in the algorithm for static analysis for large displacement option turned on while in the nonlinear or sim premium, nonlinear solver, it's actually using the Newton Raphson method. So it's it's something unique in this static solver with that option on. Yeah. There's definitely other strategies as well besides Newton Raphson that we have in there, but, but, yeah, that that's a really good point. So, yeah, thank you for that, Nick. Alright. What do you have for us? Yeah. This is a good one. I kind of, again, under the, the umbrella of dynamic analysis. So what connection types can you do for a dynamic analysis? So the again, these are connection types, that you can do for dynamic analysis using SOLIDWORKS Sym Premium Dynamics. And the answer is and for the the Family Guy watchers out there, the answer is not Picard's flute. That's awesome. Anybody actually watch, this Family Guy? They'll they'll get this joke for whatever reason when they were on Family Ties. They asked, things that you give as gifts things that you give as gifts, and I don't know. For some reason, Peter said, Piccard's flute. I don't know. I I looked that up here this morning, and and I don't know if you knew, but, the Piccard's flute went, on an auction on, like, Christie's auction house or something 2 years ago. Okay. $48,000. So some some some crazy. So, yeah, so I'd rather get give someone flowers here based off of that here at at jewelry. But, and a car, I mean, a car costs as much as that darn flute now these days. Yeah. So anybody else that has the gift the idea of that they need, just go with Picard's flute. No. I'm just kidding. Anyways, going further with an answer to this question. So the answer is, the the answer is kinda depends on what type of or what of dynamic analysis, you're choosing to use. So for for both local and component interaction options, you have bonded and free as your as your only options when you're doing linear dynamics. For nonlinear dynamics, local interactions, you can choose contact, bonded, free, and shrink fit. But for component interactions for nonlinear dynamics, you can only choose bonded or free. So I thought that was interesting. I I real until I actually really narrowed down or took these screenshots, I didn't know that even in the local or component interaction, there's some limitations between one and the other. Yeah. I I always uncheck myself, man. It's a little bit Yeah. So much there. And to go a little bit further, go ahead and click next here, you will see for all the dynamic study types, you can do here is it's listing of the additional connectors types that you can choose from. So it's interesting, what is common in all and what is not common. So as you can see, what's common in all is the spring, what else? The pin connector, and across yeah. The it seems like across the board, the bearing, but, the bearing actually falls off for the nonlinear. Which is weird, but then you get the bolt in in nonlinear. Right? So what's the heck? And then you get the bolt. Yeah. So that's a good point. So for all linear dynamic studies, you can't use a bolt connector. But as soon as you switch to nonlinear dynamics, you can use the bolt connector. It's like, What just happened there? So yeah. So it those again, these this is a question that we'll get and, you know, the curiosity of why, you know, and we just wanted to go a little bit further and show you what options you did you do have to choose from. Great. Thank you, Nick. Yeah. So, really quickly, I wanna add. I did that webinar on bolts last week. It's gonna be posted in YouTube, hopefully, sooner than later, but I do have some strategies that I go over for, on a linear dynamic analysis. If you did need to put in a virtual bolt, Some strategies you can use using a pin or a or a bonded interaction to kinda get a similar response. So I kinda tested it with the frequency response to make sure it is semi rigid in the same way as a bolt fastener would be. So it would yeah. So so definitely stay tuned for that. It's gonna be on our YouTube channel in the next couple of weeks. I'm I'm hoping. So I wanna get that cranked out. As soon as we get marketing to release the video, I'll get it ready for you all. So so yeah. So I thank you for that, Nick. Next, one of our last, this is our last question here. This is a kind of a a trend we try to add to our show here. So, looking at our time, we have about we are gonna be going probably a little bit over the hour mark, so I wanna be respectful of your time. This is the last kind of question that we have from the the this is going to your community I'll answer, and then we'll jump into the the tips and tricks for large assemblies. So, let me double check here, the questions to see if there are any any other questions. So I'm happy to ping pong between I'm getting one of those. Here. Oh, perfect. Thanks a lot, Nick. So yeah. So thank you for helping us out there with that, while I'm running the the the slide deck. But, quickly here, just wanna answer a question from our GoEngineer community. Christian here. Molnar asked a question a few weeks ago. The question basically, he's a new engineer, and he's trying to do pressure simulations to find out if a creature of some kind, which is pretty awesome. It's gonna be safe under high pressure. So he's he's doing a SOLIDWORKS pressure simulation, but but it gives him some unreal results. And he doesn't really understand why he's getting the message. It gives us some information about the dimensions, wall thickness, and and he's only putting in one bar of pressure on the model, looks like equally, on all surfaces. And he's getting some really high deformation results or seemingly anyway on his end. He wants to know what's going on with that. So so, again, thank you, Kristen, for the question. If you're if you're on the the viewership here, yeah, I'll go we we already answered your question on the community. You should have gotten a notification from that. But just to kind of review that and explore it here for for our viewers, I looked over your screenshot a little more closely, and it and it looks like you don't have any features or options to stabilize the model. So the solver, is gonna have a hard time with this, basically. I think that could be what's going on. It's it's a guess here just because, it's a little bit on the smaller side. But this might be what's happening, and what's causing the strange behavior you're seeing. I'd wanna know, I guess, in general, first to see what version of SOLIDWORKS you're on, what service pack you're you're using. Then, when you run the study, does it take a while to run? And, and and is there basically, is there a warning about the model being unstable, like, in this just in the solver window? I put a picture of of the warning message that you would probably get on on a slide here just to show you the screenshot for everybody. But, yeah, there's there needs to be either a, basically, a feature or a constraint of some kind that will fix the model in 3 d space. So for any new users, that's, that's that's, ideally, right, how this thing is gonna be installed or sitting down, something to stabilize, the model. You you can do this by right clicking on the fixtures folder and then, constraining degrees of freedom in a similar way, maybe as if a pressure would be installed somewhere. In this case, since you may be trying to simulate loading as if this thing is under general pressure from all sides, maybe I recommend that you use an option called use soft spring to stabilize model. And this is just a checkbox that you can be that you can turn on and under the study properties of your study, definitely check that out, look it up, or we can shoot you an email, Christian. I can show you where that's at, but, this will this will basically apply a small k constant spring on all exposed nodes of the calculation, just dampening any any relatively slow instabilities or reactions that could happen and destabilize the calculation. If at that point it still fails, then you may wanna isolate a very small part of maybe one of the faces of this box. Maybe apply a very it's a little bit artificial, but a fixed geometry, which, again, is gonna introduce some artificial stress in that fixture area. But, but, yeah, it'll be okay for a preliminary study. Maybe use the split line tool to to segregate a little small face there to fix it or or pick an edge or something like that or a node. But, but, yeah, again, just use maybe the split line tool in SOLIDWORKS to kind of segregate that face. Just also thinking ahead, looking at another area, your your your information scale there looks to be super high. Maybe try editing that stress plot that you've shown us there on the screenshot from the from the community, and and just make sure that your information scale is set to true scale. This will show you the true response to your model's geometry. The the issue could be as simple as that. Right? Just upon the initial inspection there. The screenshot looks a little bit fuzzy, but it looks to be, like, 6,000 or something, something super high. So maybe change, maybe just, again, thinking out loud, just trying different things, maybe try to to try different material. If you have a custom material, we've all fat fingered material properties. That's kinda grasped at straws there. But but but overall, if if this isn't helping, maybe start doing some just some methodical troubleshooting, see if the issue is not, not, computer specific or or file specific. I I did try to recreate this in in my install. I had a on my test bed that I was testing at the time, I had service pack 1 of 2024, but I wasn't able to see the behavior on my end. So that's it could be either SOLIDWORKS environment or it could be, yeah, maybe maybe computer specific. It could also just be, study specific. You could try that. Try making a new study from scratch to see if it's a corrupted study, maybe exporting the model out and reimporting it as, like, a dummy body, exporting it maybe as a Parasolid, importing it again, and try setting this up. It's a simple setup. Right? So try that to see if it's a geometry issue, if it happens again. But, yeah, those are just some some general troubleshooting steps that you can take moving forward. But I hope that answers your question there, Christian. And, yeah, let us know. Feel free to reach out if you see this webinar or you get the notification from the community. Alright. So that's what we have prepared for us here as far as customer questions, for that segment this time around. Let's get into the main showcase here, ladies and gentlemen, large assembly simulation tips and tricks. So, yeah, one here. We'll start off with Nick here. What do you have for us, Nick? Yeah. So the, the first tool, I wanna show you is the, submodeling tool. So this tool, was will really maximize your RAM resources. So we can go from a larger or a full size model with a real low quality of course and mesh and run that to completion to obtain some preliminary results. And as a second step, we can zoom in, into an area of interest like, on this corner of the scaffolding for this, model here on the slide and inject the results on the boundaries of the corner of the scaffolding to obtain more detailed or accurate results. So the idea behind this method is that, it can calculate more degrees of freedom for a smaller region of the model. So let's move over to SolidWorks and actually show you how this works here. Yeah. Let me, stop my screen share here for you, and then we'll have you swap on over. An entire screen. And alright. Do you see my screen now? We do. Yep. We do. Yep. So just like we kinda showed in the actual slide there, it was on a scaffolding assembly. Right? So, so you you would still kinda set up a a regular FEA study, where you're gonna, you know, do your boundary conditions. So, you know, you'll do your connections, your fixtures, your loads. But the unique thing about this is, part 1, is, the mesh, for the parent study is pretty coarse. Okay? And then from there, you would write to actually engage to use the submodeling method. Now submodeling is you have to have the license of simulation professional or simulation premium to even do this. So if you don't have that license, you won't be able to do it. So if you do, you would right click at the very top of your, study tree and choose the option right here where it says create submodel study. Once you choose that, it actually opens up this little GUI interface window and says the advantages and and limitations of this. I'm not gonna go through every single one of these, but there there are some limitations that you have to take into consideration. You know, for one being it's not available for 2 d studies, so on and so forth. But this is typical what pops up. I'm gonna hit okay. And then, of course, it shows the geometry of your assembly over here. And, again, we're we're picking the components that we want to really zoom in on to analyze. Right? And then we're but for the rest of the study, we're still taking into consideration everything else to be applied for the zoomed in areas for these sub modeling techniques. So if you only care about the scaffolding or this this platform across here, this member here, and this member here, you can either left click on the geometry itself to make a submodel of, or you can go over here and left click and check mark whatever you want to make a submodel of here from your parent study. Once you've done that, and just to kinda show you the result of that here is, right, open this, activate this configuration, it will look something like this. So we chose those three components to be used for the sub modeling. And as you can see, if I try to right click on fixtures, I cannot add any additional. So if I I can only hide or show any, I guess, you could say, icons or annotations of the fixture, but I can't right click and act add a fixture. You you can't add additional loads from what I'm seeing here, but you can edit them. And then, of course, this is where you're gonna refine your mesh more. This is the big advantage of submodeling is, it's picking you know, in this case, we use split faces, and we're looking for additional stress values on these, using mesh controls on these split faces within the submodel. And then you run the analysis, and then you can look at, of course, at things like Von Mie stress. And, again, it's still taking into consideration the whole assembly to run the submodel. But everything else is is a very coarse mesh, and it brings those boundary conditions into the submodel, method here. And, of course, you can look at displacement, so on and so forth. So that is the submodel technique. Very cool. Yeah. Thank you so much there, Nick. I have to unshare. Right? Stop sharing. Yep. And then Let me, share my screen here. Alright. So I think you you got another one for us. Right, Nick? Yeah. Okay. Yeah. So the next let's let me show you how you can automate the creation of large number of interactions. Right? So oftentimes, you'll bring in these assemblies of yours, and you're like, wow. I gotta do all of this manually making of my interactions. Right? Some people are like, just turn on, component control bonded. Right? Global component global component control bonded and run with it that way. There's nothing wrong with doing that as a first pass run, but, there there is a tool that you can use to ease the pain of actually doing manual interactions or local interactions, which I'm gonna show you next here. Alright. So go ahead and pass it back to me. There you go. Yeah. It's more of a a do my do my job button. Right? Those are few and far between SolidWorks. So, yeah, that's, it's a good little strategy here to show. Yeah. So so the infamous Carden joint, if you've ever been in our our SOLIDWORKS simulation essentials training, we use the the Carden joint. You know, this one came from a full configuration. It looks something like this. And then, we use the configuration called without crank for this particular method here. But what I wanna show you is is, you know, again, the pain is, wow. I gotta make all these local interactions on all these components. So this is why people tend to use more of component interaction versus local. Well, let me show you that if you, if you right click on connections and you go to local interactions instead of using component, go to local interaction, there is this option at the top here where you can do it, do an automatically find local interactions. So by default, when you install right out of the box, SolidWorks Simulation, it will it will default use manual. That's probably what you've been using typically. Right? Well, if if you've ever used on turned on automatically here, what that does is it, you can either regulate to say within a maximum clearance, find something or just find faces altogether. I'm just gonna say find faces regardless. And then you'll in this area you can either just choose, 1, you know, 2 components or you can do the whole assembly. So I'm gonna do the whole assembly, the card and joint assembly, and I'm gonna say find local interactions. Let it loose here and it has found all of these local interactions under the umbrella of contact or it could be bonded or free that you can choose to make those contacts with. And over here, I can, left click at the top, scroll down to the bottom, hold down shift, and left click again and highlight everything. Now this is a little confusing for people to know that the next thing you have to do is you have to choose create local interaction icon. You have to physically click on that little green crosshair symbol to actually make whatever you've highlighted over here, as an local interaction. So I'm gonna left click here. Once I do that, they all disappear using contact point of view, which means no penetration. Contact equals no penetration. And now if I go to my, study tree here, it has made all of these, local interactions automatically for you. So, again, right out of the box, when you first install SolidWorks Simulation, it defaults manual. But, you know, oftentimes people forget that there is this automatically find that you can use to ease the pain of making these interactions manually. You know, I say use it and just delete the ones you don't need. You know, you can always right click and suppress or delete the ones you don't need. And that is it on that one. Cool. I got something else. I got some some other ones I wanna show here for us for this session here, Nick. Also, I understand it's at the top of the hour here, ladies and gentlemen. If you need to to, to leave the session, completely understand. These, the session is being recorded and will be posted on YouTube in our archives, and in the next coming, days or to week or so. So we'll, we'll we'll yeah. So stay tuned to see the the rest of the complete presentation on there. So if you need to take off, thank you again for joining us. We're gonna continue. We have a few more tips and tricks here and a wrap up to finish off the webinar. Let me share my screen here, and let me show the next guy, the next tip here. This is a pretty slick one. If you're if you're using, toolbox, SOLIDWORKS toolbox so so, yeah, I'm talking about, do my job buttons. If you're using SOLIDWORKS toolbox, then, you're using toolbox fasteners. You can convert toolbox fasteners to virtual connectors, or virtual bolts in this case using SOLIDWORKS simulation. So it's only possible if you have SOLIDWORKS toolbox in your assemblies. Each toolbox component has internal metadata as you know, and and so there's a little bit of it mapped to the properties of virtual connector features and simulation, and it will automatically apply the correct properties for each instance. So so you can always go in and manually adjust or spot check the created virtual connectors. Once they're created, they behave like regular connectors. The only other thing I wanna point out for this tool or capability is that it's only available for licenses of simulation professional or premium. So let me show you how just a quick just a quick little vignette on this one, how that works. I have that same model that, Nick had open. I put in some toolbox fasteners in there for us. And let's say I kick off let me get rid of the star and pop up here for the the screen share. Let's say I make up a new quick static study. I can go ahead and turn on convert toolbox fasteners to both connectors here. I can check that on, or let's say I didn't do it. Maybe I didn't realize I needed it yet. And let's say I'm creating a setup for this model. I'm putting features in it, and then maybe retroactively I decided, hey. Maybe I wanted to convert those. I'll do a right click under connections and then turn on toolbox fasteners to bolts. It's gonna give me a little summary. It's going to go in and add, and basically hide and then exclude from the analysis all the fasteners, and it's gonna replace them with those virtual fasteners here. You can see four instances of those. And, again, they're just regular bolt interaction features or bolt fasteners, bolt connector features that, and they come with all the the preload and thing. That's all taken from the metadata that's saved inside of the toolbox metadata for the part. But, yeah, that's just quick and simple, just little little pop up there for that. Let's see. I have another one here I wanna show. This is also kind of just, basically showing you the the did you know kind of feedback, and and this one was added in 2020. The sim dev team introduced, an ability called mixed meshing, and this allows you to select between a draft quality mesh and a high quality mesh on individual components. So, it'll it also introduced some color coding of the mesh. So orange is gonna be for draft quality, and then blue is gonna be for high quality mesh elements. So this is kinda nice because previously before 2020, you can only specify the setting for the whole model. So it was an all or nothing thing. So this is gonna definitely save up on some RAM resources, and it'll allow you to apply high quality mesh on parts that are maybe of a particular interest in your study or have a particular more complex response. You're right. You need all the extra d data and detail in that area you need, and then put it you can put some draft quality mesh elements on maybe some not so important elements. Not much I wanted to show about that except for when you're inside of the mesh folder that you all know and love, you can jump in. There's a new tab called mesh quality, and then you can decide what you wanna bring over and do a draft quality mesh of maybe these two brackets. And then when I click okay and mesh it, now we have draft quality for those, which are in orange. Everything else is gonna be high quality. Another place you can manage those, which is kinda surprising and and and convenient, is under the parts folder here where you select your material. You can see that, let's see if I can zoom in here for us. There we go. You can see that some of these have a little squiggly tetrahedron icon, and some of these have the straight tetrahedron icons. Those are the draft quality, and then the squiggly ones are the the second order or or high quality elements. And then we can manage them by right clicking and then showing and saying apply draft quality mesh. Now that changes that, and then, yeah, you can basically go back and remesh your model to update the geometry. But, just a kind of a subtle thing that you may have missed, from 2020. Let's go back. I have a few more here I wanna showcase for you. So the next tip is a a soft work's capability, but it's very useful for simulation. This is called selection sets. I'm surprised how many people don't know about this. Maybe it passed them by. It was released back circa 2013 ish or something like that. Yeah. It's been that old. Yeah. It's been a while, and it's subtle. Right? So it's and, also, the, the the the, there's a folder where it lives in the SOLIDWORKS design tree, and it's not on by default. So it it's on when you create a selection set. So so what the idea behind this is that sometimes in simulation or or any tool, right, not just simulation, we select the same group of faces, right, or entities over and over again, just to recreate either reader interactions or different boundary conditions. It's not a hard thing to do. Right? But the selection of the individual faces or retches, just tedious. It's just time consuming, right, especially with larger models. So so it can be frustrating. Right? You can mess up your selection, especially if you're, like, 25 faces in, right, and then you get confused or someone, like, asks you a question, you don't know where you're at or you click on something, you have to start all over again, clear all the entities from the box. And, so, yeah, that that's especially true if you're gonna be troubleshooting interactions or or other boundary conditions. It just can be a pain in the butt. Again, not a not the end of the world, but it does take some some time. Right? It takes a little those repetitive clicks can add up after so much. So if you find that you are redundantly selecting the same SOLIDWORKS geometry over and over again, then, yeah, this might be a good idea to quickly create what they call a SOLIDWORKS selection set. Let me show you an example. So this is, again, a SOLIDWORKS utility or functionality. I'm gonna jump back over to the SOLIDWORKS tab. And then let's say that I select a couple of faces, maybe those faces, just kinda randomly, in this case. And while they're highlighted, I'm holding the control button down to select those faces. I can do a right click and then choose from the right click menu, save selection, new selection set. That, if it's your very first selection set created, we'll make a new folder at the top level of the SOLIDWORKS feature design tree. It's called selection sets, and I've made a couple in there myself before. Here's the one I just created. I can do the slow double click to rename it. I can manage these by maybe adding to the selection set. I can select additional faces, and I can add to selection if I needed to. So I can do that. I can manage the selection faces here as well. So I can delete them. I can delete the whole selection set if I needed to. But but, yeah, now that you have an maybe in this case, some internal faces that are kinda hidden, maybe I'm doing up a a custom load somewhere or or some sort of constraint of some kind, and maybe I wanna select those kind of hidden faces. Well, now I can expand the abbreviated SOLRICS design tree, and I can click on those internal faces and quickly pick those up, or any side faces or just anything that, that you've already preselected and saved. It's very handy. It works across the board with any SOLIDWORKS feature in product, not just, simulations. So so it's just a real powerful tool. I've seen people that do, pressure vessel analysis where they have to put pressure loads on a tank all over the the the inside walls. They'll do a Very cool. Yeah. That method of Selection sets. Selecting those selection sets ahead of time so that when they do their pressure load, they they just click on that and highlights every one of them and on they go. Very nice. Yeah. Yeah. Or how internal housing faces for something. Right? Yeah. There's a lot of lot of Yep. Opportunities for that tool. I got one more for you here. One more, large assembly feature tool. And, basically, this is, this is the last tip for for our session here for this section. So let's talk about the fact that you can import your already created simulation studies that you've done up, maybe in a part file or a subassembly, and you can bring them up or graduate them into a top level assembly. So, basically, you can reuse already created boundary conditions or features, and help with, say, the setup time of your larger assemblies, so that, yeah, so that you don't have to redundantly recreate those constraints or features. So this is done in 2 ways. You can do it upon the the initial creation of that study. So you can just click there's a checkbox that I can show for that I'm showing here for, for import study features. Or if you've already created that study, you can just go in and right click on the top level of the simulation design tree there, and you can access that functionality as well. So, so, yeah, just whenever you have that open, it'll bring open it'll it'll pop up this particular window there. And so yeah. Yeah. The the window then will give you this listing of, different, parts or subassemblies that have features that you can recycle and and graduate in bold. Here, you can see the base plate. At that point, you can go in and you can go to the the right hand side. There's some additional filters if you wanna specify specific types of features that you'd like to include in your import, and then just click the import button. It's as easy as that. I've just kind of set it up here with this particular model. If you if I open up this particular model for you, I have a study. It's a little simple static study to show, and I have a couple of features in there. I have, maybe a foundation bolt in there. I have a force load. I think that's about it. I mean, oh, a mesh control as well, so I can bring in some mesh control stuff. So now when I go to my top level assembly so when I go to my top level assembly here, I can just start off with that same static study, and I can right click and select import study features. Here's my little window that you saw in the screenshot earlier. You can see that the base plate is the only one that has any features for simulation I can graduate. I select the radio button, choose what I don't want to include in here. Maybe I don't want the mesh controls or or a force load, but then I can say, hey. This is the study type that I wanna bring in. Click import, and that's gonna import it into the active study or current study. So it's it's it's not connected in any way. Yeah. It's really, really helpful. So I we we we're just trying to eliminate human error here. Right? Because that's that's one of the biggest things that I I I remember seeing when I was in tech support. We have a lot of repetitive things we have to do. Right? So all these tips are geared towards that, I feel, all these productivity tips to help eliminate human error. Any questions on that? That was the last tip here for us. Alright. So let's go on back to the presentation and have some closing statements here. So but, yeah, yeah, that that was our show for this today. So, again, thank you for joining us a couple minutes late here, this, this morning or afternoon or afternoon, I think, for most of us now, here at the SOLIDWORKS Simulation Symposium, where we talk about all things simulation related. So we'll be putting out the the show, like I mentioned earlier, on our YouTube channel soon. So if you needed to review anything that or if you've missed a segment, it'll be there for your reference. So we also have many other, simulation related presentations like I we've mentioned as well. Other tips there, including just fun projects as well that some of our other, colleagues have been working on. So definitely check it out. If you prefer to read your content, I invite you to check out our Goengineer YouTube or excuse me, our Goengineer blog here for just from goengineer.com. A lot of content gets put out there as well as technical articles, best practice articles, fun things that are are again, our colleagues have been working on, 3 d printing and scanning. I think I saw someone 3 3 d three d scan their body and made a made a Wonder Woman costume for Halloween 1 year. So I think, yeah, that's up there. So there's, yeah, there's a lot of fun stuff too if you just wanna take a little break there from the, the day to day. New stuff too. Yes. Thank you. The what's new stuff will definitely be up there as well. But, yeah, that's all we had for us today. We'll stay on for a minute or 2 to see if you have any other last minute questions, but, we'll do our best to to help you get a decent answer here. But, again, thank you all for attending today, and we'll see you on the next one, which should be December. Right, Nick? We're gonna do another of these Oh, yeah. December 1st week of December. So stay tuned for that, everybody, and, have a good, good rest of your week. And we'll stay on here for, yeah, another minute or see just a minute or 2 to see if we have any questions from everybody. And thank you for all for joining. And, I have a question. Yeah. Let everybody let us know if you liked it. What would what would you like to see more of? Absolutely. Yeah. We're looking for topics. Absolutely. If you like more of these, we can look at more large assembly tips or just just simulation tips and tricks. We're gonna do flow simulation in in the next show, but we can also incorporate other items as well. So, yeah, thank you. Thank you, Anand. Thank you for the, for the feedback. We're, Yeah. We're happy to be here, and and share what we know. So it's cost us a lot of sweat and tears, right, blood, sweat, and tears to find out this information sometimes. So we're happy to spread it out. So you're interested in drawings. So, yeah, I mean, we could we could, what Specifically what? And for Yeah. Was that under the umbrella of simulation, Hernan? Or was it just SOLIDWORKS drawings? I'm sure we can we can scratch up someone to, and people are looking for topics if it's just SOLIDWORKS CAD drawings. We have a lot of good people that can do something. Tips for more efficient. Oh, okay. Yeah. I'll I'll I'll make a note of that, and then we can put that in, we have a list of of topics that people ask for things that they need, topics on. So, yeah, that's a good good one. Especially, I was getting ready to ask you, Hernan, what what specifically and I I I was assuming large assemblies, and you hit the nail on the head when you when you said especially. That's usually what it is. Large assemblies and drawings. I get it. Yeah. Those can take a long time. Right? Yeah. Even to even to open. Like, I was at a customer, meeting just in person. You know, just just helping out. I I do some some Solrick stuff as well, when I can, to keep that as sharp as I can. But, but, yeah, they were having technical drawing issues. And Isn't that what's that new there is a new, way to load in, like, a lightweight mode, load drawing at, like 9 largest design review, in drawings. There's, like I think I don't know if it's popular anymore. I think it was called detached drawings that you can use. It was something new in 21. The link. So oh, yeah. Yeah. There's what was that where It was like I think it's like a visual thing only. Right? Yeah. But it's still I don't recommend that. I think it's it goes against ASME 14 145 or 143 best practices. I I did go I did yeah. Yeah. I I see what you're saying. It is convenient, but I think it's not a good practice from what I've seen in other documentation and from other engineers' feedback. But it is handy if you wanna do quick no. No. No. It it is quick and dirty. I think I had a customer that, when I went on-site that was using it. And if you need to get by, it could be a good tip. So Yeah. Yeah. No. No. It's good good to know about. But, yeah, I mean, we can expand on that, Anand, when when we get to it, and we get to someone to do a webinar and stuff like that. So, yeah, we we do a lot of webinars, I've I've noticed. So there's there's a lot of people looking to make content, so it's good to have feedback. Any other questions? Or comments? Yeah. Hope we got a lot out of this. Yeah. We appreciate you all, and, I know it's a bit a bit of a long one here. So, but, yeah, we'll we'll keep sharpening our tools and keep, keep bringing value to you guys. We wanna give you guys something that's useful. If we get questions that we think are gonna be important for the community, things that we get asked a lot, I would just like to share it because if one person has a question, a lot of others probably have the same questions. So that's, yeah. Alright. I think we're gonna call it, Nick. What do you think? Yep. Let's do it. Well, again, for those of you that are that are sticking around here, thanks again, and have a good rest of your Thursday. Take care, everybody. Thank you. Have a good one, everyone. Take care.
