[SOLVED]help NON CONVERGENCE non-linear geometry (Contact problem)

Hi,

I've been having troubles in a contact problem in the geometry convergence. I play with the time step, contact formulations, etc. but still not converge to the RESI_GEOM value (1e-3). Does someone have any hint on this?

You can find the .mess and MED file attached to this post.

Regards,

Guillermo

Sorry, didn't see that the file was missing. Although, I've found the solution, I just had to change the time step for the Newton's method to converge and switch between the master and slave surfaces. Nevertheless, here are the files in case someone needs it.
