Static non-linear analysis results all the same
I have set up an analysis with three parts in it. They are connected to each other with a combination of contact and bonded interfaces. I created 6 g-load cases of varying magnitude and direction....

Re: Static non-linear analysis results all the same
Start in a clean directory and run 6 g-load cases on just a single component and see if all the stresses are the same.

Hi, Simulate can only have a single g inertial load acting at any one time whether or not linear. This is not a limitation if one considers that at any instant (d'Alembert) all loads sum to zero, there...

Hi, I am rarely asked for signed von-mises and is usually associated with fatigue calculations. This time I am asked for signed vm from simulate. There is no handy quantity selection in the post...

With a non-linear study, it will refuse to run with more than one g-load case, and gives me this error: "A summed load set can not have more than one Gravity load.". I can run all the cases in a...

That's true for non-linear, just one run per study.

The results are different from the original runs, now, but they are all the same to each other again.

Re: Static non-linear analysis results all the same
Summing the loadsets that each have a gravity load will give you the same 'error' whether linear or non linear. I thought it might be useful to have a bit more detail, apologies if you know all this...

Steven, Did you ever get this figured out? I'm fighting a similar battle right now. I've found a spreadsheet for download that looks a lot like the one from your screenshot. What I need to do is fully...

Zachary, Yes. The Mathcad folks resolved it for me. I have attached the solution in the link. https://www.ptcusercommunity.com/thread/135231

All, In NASTRAN/Femap, there is an option to report stresses per the element average, instead of the corner/edge values. Is there a similar way to do this in Creo Simulate? I regularly run into...

Of course I can do the sphere in Creo, I am just testing another modeling software. So, it is not meshable and that's all? Any important aspects while trying to import objects into Creo, can someone...

Thanks for all of you, these are very useful informations for me. I will use it in the future. An other question: I simulate a sheet metal bending using non linear material of course. My first test was...

Ruben, You cannot import polygonal mesh data into a BREP solids MCAD modeler. MCAD modelers can only import useable data from other MCAD programs and not from simple mesh modelers or 1985-era OBJ...

Erick, By default, Simulate averages the stresses in the elements, unlike Mechanica, where the operator had the option to view averaged or un-averaged stresses to check for continuity. I currently...

Ways to prevent rotation in Simulate (Creo 3.0)
Hi, I am analyzing a shackle that is pinned to a bushing. The assembly has 2 rotational degrees of freedom. For the analysis, I am simulating a strap pulling on the shackle with a force on the...

Derrick, You have to permit rotation of the pin and yellow part. You have to permit rotation of the shackle. There is chance are that there will be large movements and you may need large deformation...
