Large deformation of a 2-D square

Hello All

I am trying to apply a large shear strain on a square domain. The geometry is very simple, just a square where on the upper and lower edges, opposite velocities are applied. In order to prevent any rotation, I assume that the upper edge is fixed vertically, and I turn on the nonlinear geometry option.

I get divergence problems and to solve it I have tried every possible method (adaptive mesh, automatic refinement and even mesh displacement physics), nothing works. The process stops at 13% progress.

Thank you,
Hossein
