Hi

I'm trying to run a motion analysis on an assembly. About 0.2s into the simulation, I get an error message saying:

Number of new element states 2 doesn't match number of old ones, 3.

The simulation stops and refuses to proceed further. Does anyone know what this might mean? From the animation, I see that a part (solid) protrudes to another part (solid). I've already specified all solid contact components though.

Thanks for the help in advance.
