Hello Array,nI hope you have implemented the suggestions (keyopt options) mentioned in Peter's video https://forum.ansys.com/discussion/18002/convergence-during-large-deflection-of-hyperelastic-materials. Also have a look at https://forum.ansys.com/discussion/708/convergence-issues-highly-distorted-elements. You could set identify element violations to an integer value, see the distorted elements and increase the mesh density in this area. Not sure but from the image it looks like the corner elements are distorted, try using a mesh bias to cluster more element. Try using a displacement instead of pressure and see if you get the same error. There also seems to be a slight pene tration at the top right corner, please check the contact settings and reduce it.nRegards,nIshan.nn
