Hi everyone,

I have a problem with a non linear simulation.

I want to simulate the contact pressure of a disk in the surface of a cushion, but the solver always has the same problem.

I attach an image to prove it.

I modify these parameters in the simulation:

1. Materials: Cushion --> a TPU flexible Mooney-Rivin Model hyperelastic

                    Disk --> Iron

2. Conections: local interaction--> I select the surface in contact,
