Hi,
I have an issue in 2023 where the solids that are shelled still participate in the contacts, meshing and results.
note solid on the left, solid + shell on the right:
Update:
It appears to be related to FEA.iam < weldment.iam < multibody.ipt
If I do FEA&weldment.iam < multibody.ipt then the issue does not occur
