I am working on a hyperelastic simulation in ANSYS workbench, refer attached pictures for details. The problem is confined to 2D. The right geometry is an elastomer (defined by Yeoh's model). The left one is fixed and is Aluminium. The elastomer should be supplied high pressure (~7 or 8 bars). upon its expansion, it will make contact with the Aluminium surface and i need to look at the contact pressure.

I am getting error message as shown, I refined the mesh, see mesh quality attached. Also I increased pressure very slow. The sub-steps are large enough. Can anyone troubleshoot the problem?
