Hi all,
I tried to learn on hyperelastic material, but at first with thk of 10mm, i can only apply 20mm displacement for convergence, otherwise it wont converge...then i change the thickness to 30mm, the behaviour also same..it can only been applie for ux displacement up to 20mm.

what should i do for higher displacement in ux?
thanks
