Live simulation uses GPU for calculations. That’s why its called “Live”. Where as Application simulate is a CPU based solver that has the ability to iterate to higher order elements. Application simulate is far superior to live simulation for large assemblies as live simulation has the risk of un-converged output. Simulate on the other hand has capabilities to achieve set % of convergence. Main difference is Simulation live uses H type mesh (element based) and Simulate uses P type (nodes/order based). Although H type is industry standard in most FEM solvers, P type is kinda effective at achieving convergence with coarse mesh. On top of everything else, Simulation live is based on Ansys.
if the welds are intersecting each other, the model is not getting meshed. I tried adjusting length for each joint to avoid any interferences . Is there any other way to do this? because there are a lot of welds in my model
Unfortunately, there is no shortcut to do that. One has to shorten the length of welds in the weld definition itself. Another method is to use weld as a part by creating sweep features.
Hello sir, I would like to ask how to modify the accuracy of the weld entity. When I checked the tolerance report, I found that the tolerance of the weld was too different from that of the part, resulting in a series of errors. Thank you very much😀
Usually, be consistent with tolerance between your parent bodies and weld should be fine. Welds are pretty accurate when joints modelled correctly. Convergence could be a topic in itself, which I will may be cover is another video.
@@nothingbutengineering Once I created the weld features within Simulate/refine model, the review geometry errors saying there are detected bond interfaces between several mated surfaces. I've already created interfaces and review geometry was clear, but after adding it errors. Any suggestions?
In Analysis tab, there is something called global interference check. In case if you have welds at close proximity in your model, it’s better to get it checked for any interference. Thanks! Great that you fixed the issue. kudos to you!
Extremely high quality content! Thanks a ton 😊 But one question though, we choose the component butting surface as FREE, shouldn't it be Contacts? I ask this question because PTC help states that FREE interface allows the penetration of nodes, while CONTACT prevents it. Do let me know your thoughts.
Good question. Most thin solid (sheet/plates) problems are linear problems and avoiding contacts will make sure most of load is going through the weld. While using contacts, friction may absorb some of the deformation or force. Also, using contacts forces you into non linear problems, which is not good for evaluating fatigue loads. But when you are interested in yielding and plastic deformation, its sensible to use contacts.
@@nothingbutengineering What if you use No Friction - Contact interface? In that case the Contact interface will not absorb any deformation of the face. It's a very good question and I would be happy to get a more in-depth explanation. Thank you in advance.
@@Druze_Tito Contacts are primarily used in non linear problems and for impact loads. For fatigue and eigen value problems, they are not preferred. And, Creo is not very good at handling contact non linearity.
@@Druze_Tito Yes, they would be close to real life if we can have that option in solvers. I am not an FEA expert so I am not entirely sure of whether other solvers apart from simulate have that kind of fidelity while solving. Need to check. Anyways, thansk for bringing this up! Intriguing one.
Thank you so much for being the only person on UA-cam to provide a detailed and proper explanation of Creo Simulation.
You’re most welcome !
good explanation bro keep doing videos like this.
Very nice video, concept clearly explained. Please make more videos with more complex design problems
Thank you, I will
When you apply gravity, is it applying forces for the weight of all the components as well (via material properties and geometry)?
It will apply acceleration about centre of gravity of the entire model, based on material density and geometry.
Hi sir, I am using Creo Live Simulation what difference between Application Simulator vs Live Simulation.
Thank you for sharing this valuable Video

Figured it out. Weld features were intersecting each other. Had to reduce weld size.

@@nothingbutengineering I understand. But wouldn't the results be more 'accurate' to say per-se?

Hi,
How do you rotate the modal so smoothly,
Is there any shortcut for that??
3D mouse
Hey there, I use 3D connexion’s space mouse.
Can't you just hold the middle mouse button to rotate to your desire?
Thanks for sharing :)
