Hello again,
so I followed your instructructions and activated the contacts using the settings shown in th figure below. But for some reason no matter what Lagrange formulation I use for the contacts I use, I always run into convergence problems. The most complete result (0,91s) was achieved when I set the contact behaviour to asymmetric with augmented Lagrange formulation using the programm controlled auto-time-stepper. Attached you will find the updated projekt-file. Maybe you can have look again peteroznewman? Thank you very much
