I have a model with solids, the calculation reports a singularity. How do I fix this model?

Answer

The solids are connected by using surface release with the "fixed if negative pz" nonlinearity. The force pz is derived on the basis of the orientation of the contact surfaces. If the orientation of both surfaces is the same and you want the compressive load to be transferred between the surfaces, it is necessary to use the "fixed if positive pz" nonlinearity.
