Constraints on contact surfaces?
Constraints on contact surfaces?
(OP)
Hi, I have two contact surfaces(Master-slave) with normal-Hard and tangential-Rough interactions.
How can I constrain them or I shouldn't? (pin-contact problem)

Sometimes, the job is completed if I didn't constrain the two contact surfaces and sometimes it just aborted.

Initial step:converged
Step 1:Converged. (To establish contact among surfaces)
Step 2. Not conveged after several increments.
I already refined the meshing, decreased the initial increments(0.1), and used the contact controls. It sitll couldn't converge.
Error message:too many attempts. 0 pivot.over constrained.

Error messages:
Time increment required is less than the minimum specified
Should I make it smaller (1.E-6)?
