Using a Nonlinear Static Analysis, I want to run a simulation using two subcases:
Subcase 1 - "tighten" the bolt using an enforced motion displacement.
Subcase 2 - "lock" displacement between the bolt and the base via a bonded contact, then apply load to the cylindrical body.
It seems I cannot enable and disable contacts between subcases? Can anyone think of a workaround to accomplish what I'm trying to do?
