I am trying to simulate a 3D problem which involves structural and thermal multiphysics. I would like to create 2 concentric cylinders which the inner cylinder expands more than the outer cylinder when heated. Right now if I do not specify the contact pair, the inner cylinder will simply go into the outer cylinder after the simulation which is unreal.
If I try to include contact pair, the simulation cannot be solved and the following error message will appear:
All variables solved for must be treated in at least one segregated solver step."
I would really appreciate it if anyone has experienced this and knows how to solve it.
