Luis,
Here I have opened a part in Creo Simulate Legacy Structure (a.k.a. "Mechanica independent mode", i.e. the old original CAD-independent version of Creo Simulate.
I meshed it, and then I picked a few elements to hide.
Here you can add solid elements (or any other modeling entity) to groups that you can hide or show. In this case I didn't create a group, I just clicked "Hide items" and then "Solids" and then I picked a few solids using box select. This way I can display or hide elements of my choice.
It's tedious to work in the old UI, but it has some advantages. In post-processing it is also possible to extract stress results for specific elements etc.
(Executable: <Creo 2.0 loadpoint>\Simulate\bin\simulate.exe")
Best regards
Mats Lindqvist
