How to solve contact-pin problem?
(OP)
Hi, I got this error while modeling circular pin-contact problem. How can it be solved?
Solver problem. Zero pivot when processing D.O.F. 1 of 1 nodes. The nodes have been identified in node set WarnNodeSolvProbZeroPiv_1_1_1_6_5.

and make sure that your model doesn't revolve ( check your BC's)

I already used 1.E-6.

I'm not sure why pooya suggests a non-linear solver for applying a pressure, or what that is. If you have any non-linearity in the problem such as large displacement or yielding then it's best to remove these to simplify the problem and to identify the source of the problem with contact. Add them back in later once the problem has been fixed.
