In running a simulation on the attached assembly, the displacement I should be seeing is less than a millimeter.  In actuality, I am seeing MUCH more.  After running for about 30 minutes, it tells me it can't reach equilibrium, then asks me if I want to solve as a large displacement problem.  I say no, then it gives me a resulting displacement of 1 km.  Apparently, my contact sets aren't working, but I can't see why not.  Can you help, please?
