I need to simulate multiple contacts between complex geometries.
For this, I cannot use the more recommended approach of creating native contact geometries within ADAMS itself.

If I have to give contact between imported geometries (from Creo), which is the best format of import?

Normally I would think of parasolid, but the wireframe view shows the solids as rough and coarse.

I was thinking of importing in .stl format (which would get converted to .shl shell geometries in ADAMS).

Does anyone have any experience with this? or any recommendations for me?
