Haha your description of a overcomplicated first study that ends in disaster is exactly what I did... I thought it was simple, but it was not, and I got bombarded with error messages.
I call this the "initiation ceremony" stage for simulation. Just don't be tempted to click "yes" on any "excessive displacement" messages. Hopefully you can scale down reasonably well and keep trying!
If I had gone a little further, you explain that contact "used to be" No penetration. Still need to know about constraining and the excessive displacement problem.
I am running 2020 Simulation Standard. When changing the bonded contact, my selections above and below bonded are No Penetration and Allow Penetration. I'm selecting No Penetration because that seems the most reasonable. I'm also trying to find out if they changed the names for 2021 or another time. I don't recall you telling me which version you are running. I wish I knew that information and would like if everyone presenting a webinar would be specific about what version they are running during the presentation. I also had some difficulty with Static 2 that yeilded "Excessive Deformation". The error said, "If you are properly constrained..." When I opened the tutorial file, all the parts had constraints that were suppressed and fixed. All the parts in your model are fixed. Does that make sense? Seems like there should be something keeping this assembly together besides the magic of fixed. Further, there was no key on the downloaded shaft. I put that on myself for Static 2. How should the assembly be constrained when analyzing the stress? I would like to examine real world situations, not reasonable facsimiles there-of.
Hello Dudley, First of all, thank you for spending the time in writing your comment. I've tried to address many of your points below. I hope this helps rather than overwhelms, but please let us know if you have any subsequent questions. 1) To identify the version used in presentations, look in the status bar (the bottom left corner of the SOLIDWORKS interface). When it's not giving some instructions, it will show the version. In this presentation, I am using 2021. 2) As you have pointed out in a subsequent comment, I mention the name has changed for contacts. 3) You mention about parts being fixed with constraints suppressed. You are likely referring to the CAD constraints and not referring to constraints in the simulation study. SOLIDWORKS Simulation does not use your CAD constraints (mates and "fixed"). Instead it reads the positions of the bodies from the CAD and then it uses the simulation connections and fixtures you may add to your study. 4) The excessive displacement warning occurs if your model is unstable. Almost always click "No" to this message and many times this will help give you a sense of the problem. Did you enable friction like I did? Perhaps a small additional Fixture will help to keep the components from sliding off of one another. There may be a variety of ways to address the problem, but see my next comment below. 5) Real-world simulation whereby we may attempt to model every gap, corner, fillet, contact, etc. is often unfeasible. Many times, we need set up simulations in a simplified manner and slowly build the complexity to APPROACH a real-world simulation. Using this method, we may determine if modeling a full real-world is practical or necessary. This approach is more manageable, especially when just starting out with FEA. If you try to do real-world simulation as your first study, you may get overwhelmed with complexity and give up quickly. See my discussion at around 7:00 for the basic idea of why I'm starting out the way that I am. I hope this presentation is enough to get you to be able to run some simplified studies to start with. For more detailed coverage and more examples, you might consider taking a look at the content of one of the training classes where we discuss model instability, other elements types, design studies, thermal loading, and a wide range of other topics.
Hello, how to use graphics card to do the computation any simulation (e.g. static study, topology optimization etc)? I have a low processor(intel core i5 13400f) with 16 GB RAM, and GPU RTX 3060. Thank You.
The models used in this video are actually tutorial models that you can find by going to Help, SOLIDWORKS Simulation, Tutorials. I altered the workflow of the actual tutorial and added the "key feature" to mine. As extra practice, you may need to do add the same to follow along completely with my methods.
99/00 was sotNice tutorialng called Vision DSP or DST or sotNice tutorialng and didn't quite work the way soft soft does, but tNice tutorials video helped so
Thank you! Nobody could have explained all these more clearly! You are a great tutor!
Excellent video!! best video to begin simulation and force analysis learning on TH-cam.
Still helping after 2 years

@@goengineer It's mostly a lack of time to mess with it.
thanks for your uploaded video, it does really help me to know basically simulation in Solidworks.
You are welcome! Hopefully this gave you a good head start!
Cool tutorial, well done, thanks :)
Nice, thank you so much!

very good tutorial, and good, that they are not the std examples from solidworks :-)
Glad it was helpful!
I started making soft recently, I was wondering if you wanna do any features.

SW Simulation does not currently use any GPU for calculations.
Thank you
whenever i start playing softs or tracks its mute
Thanks you bro. love you....
can you plz also upload part files used in every video too ?...That would be very helpful

I also really like softEX, it has a very nice effect to it

What computer are you using? My laptop took 1 minute and 23 seconds on Static3 (Contact). It's a 500 buck laptop.
I'm using an HP Zbook with an i7-8850H CPU
You never know how much you have in common with so people.
I didn't receive email regarding this webinar
TNice tutorials guy explains tNice tutorials better than teachers explain good eating habits
The soft of Gaia it really isn’t
"Welco-"
thank you so mush (GoEngineer team)
