Is it possible to see stresses in an assembly and move the parts (in order to see what is under a parta for example). I know that such a feature is available in Solid Works for example.
You can control the visibility of meshes and groups in postrocessing to turn off parts of the model in post to see the results that are hidden by a geometric part.
Please check in the Simcenter Documentation
You will find information on how to control the visibility of meshes, mesh types and groups.
I hope this will help you performing your postprocessing.
