Altair EmployeeHi Mario,
the simulation is working now. Thank you!

Hello,
your example is not really nonlinear (except contact), so NLGEOM isn't the favor. (Try NLSTAT instead).
But you can run the example with NLGEOM, i have maked the following changes:
Material: input a Nu (i have tried 0.3 for both materials)
Geometry: put the parts together (no big gaps between the solids, maybe 1e-3)
Contact: change MORIENT to opengap and SRCHDIS to 0.1 (a little bit bigger then the gap)
Boundary conditions: constrain the upper plate also in X and Z (otherwise there are to many unconstrained dofs)
NLPARM: i have set NINC to 10 and MAXITER to 25
