Hello, SIMILIA Community people

I am solving a compression test (3D RVE model). My model is the cylinder enclosed inside a cube. I am solving with periodic boundary conditions. When the displacement is applied from the top (Y), the problem occurs at the contact region and the job aborts. I applied a displacement value of 0.1 mm for the 1 mm model. Later tried with 0.05 mm displacement.

It works properly if I do the compression along the sideways (X or Z). Only the compression in the Y-direction creates a problem.

Need suggestions to tackle this?
