Nonlinear Simulation Error: Stiffness present on nodes not element 360603

Not that error message specifically. I do see it failing in the first time step though. This could be due to too much movement in the first step, the part is over-constrained so you're producing a lot of stress when trying to move it, or the material definition is no good.

I also see that you've got 2mil DOF. Can you simplify the assembly or mesh while you troubleshoot?
