You have to apply the boundary condition to the rigid body constraint’s reference node instead of the underlying face (since this results in an overconstraint):

However, the remaining two parts are not constrained which will lead to rigid body motions and non-convergence. You could tie the parts for now or apply sufficient minimum BCs to them (depending on what you want to model here).

Also, the mesh needs a significant refinement.

Just an example (I’m not sure about your goal): [TEST1\_mod.pmx](https://prepomax.discourse.group/uploads/short-url/gAzX8gbvwWHpf6EFZHHXSji6cne.pmx) (8.5 MB)

Ok, I’ll try to help with it.
