Patran to Ansys Workbench Migration

[Kurunful]

Hello and good evening,

At work, I was asked to perform "migration" of 3D Patran models to Ansys Workbench, using SAMCEF V15 for processing in both cases.

But I have been observing a disparity between certain displayed values:

To be clear, I take the same files and inject them into Patran and WB then proceed to taking the critical values at every time step at a given model. While the values at the nodes are the same, whenever I have to get a value on an element, I get a gap of 0.01-0.5 which I wasn't expecting at all since they're the same files and that the processing is done by the same solver.

It gets a bit worse when I migrate the boundary conditions from Patran to WB, generate a .dat file from Ansys Workbench and then read the results that come from it: the gap widens.

Although I post-treat the model regardless of the regions of boundary conditions, the results are just not the same. I sometimes have to post-treat only a surface on WB -the one in Patran where the critical value is located- to finally get such value.

Can someone please help me understand what is going on and what I can do to improve it?

Best regards,

K.
