Mesh Question
Hi,Looking for some advice or clarification that I understand how Mechanica works with respect to meshing.I have created a simple test part shown below and gone through many of the mesh settings to...

Hi s, The best way to answer your question "is it sufficient" is to run an analysis using Multi-Pass Adaptive, and look at the convergence graph. If it levels off smoothly before reaching 9th order,...

It looks like your model is not that big, so run an analysis for each mesh, and compare the results. Then show the results to your colleagues. And post a copy here

Apply Moment, TLAP Menu not available
I´m trying to apply moment to a part but the menu to select "total load at point" is not available. I checked it with my colleagues where it works but on my workstation/installation/config it is not...

Re: Mesh Question
Thanks for the response guys. I'll pay close attention to the convergence graph in my analysis. Appreciate the 'Edge Length by Curvature' advice also. I'm going to be doing this on a much much more...

As Jonathand mentioned, run a MPA-analysis, create measures of the quantities you are interested in, and see how those converges as the P-level is increased. If a mesh is "sufficiently dense" is...

Re: Mesh Question
In that case also demand of your colleagues that they do the same, so decrease mesh size and compare results for each mesh size. If the results no longer change it shows that the mesh size is okay....

COMPARING RESULTS OF DEFLECTION IN CREO VS HYPERMESH
I have tried to do a chassis analysis in Creo Simulate using beam idealization and same in hypermesh but when I am comparing the results both show different value for the same loading scenario.can any...

For modal analysis the mesh size is much less of an issue than for stress analysis. Basically you only need to get the stiffness and mass distribution right, so for most parts (in H-elements) any 2nd...

This is impossible to answer without more information. Tell us more about the way you modelled the chassis and the loading you applied?

How to fix degenerate boundary faces in Simulate
Hallo, anyone knows what is this kind of problem and what is it due to? (here below the screenshot) how could I fix it? thanksbye

Re: Mesh Question
sjohnstone, I ran your test model with my own boundary conditions and mat props, and as you can see in the below images, there is very little change in the solution and convergence. I made three...
