Discrepancy in Results When Applying Moment with RBE3 in 3D Model

berchiche

Hello,
I am currently facing an issue with the results obtained in Code_Aster. I performed a 3D modeling study where I used a contact condition and the RBE3 function. The goal is to compare the results with those obtained in Ansys Workbench.
When I apply a force, the results match those from Ansys. However, when I apply a moment, the results differ, and I am not sure whether this is related to the 3D modeling approach or to specific characteristics of the RBE3 relation.
If anyone has insights or experience with this type of discrepancy, I would really appreciate your help. I am attaching the .med file for reference.

If you post a runnable input deck, not just the mesh, I can take a look. I use RBE3s a lot, but application dependant.

I try multiple times uploading the .hdf file but it is too heavy that's why i uploaded the .med file with all the commands i used . If you can help with just this one i would be very grateful thank you

yes, in this forum better use a link to an external cloud drive, whichever you like. This forum is quite limited in size, types of files you can pop into a post....

I only need the input mesh, med or whichever format you used, and an input deck (.comm file) that runs your end.

Update: I see, your 1st .txt file was the deck; so only left is whichever (I assume MED) mesh file you used here: LIRE_MAILLAGE(UNITE=4).
