Dear All,

I am trying to solve a thick rubber ring to seal two parts. I am using half symmetry model and applying pressure in the ring OD using a metal ram. When I try with data check run quarter portion behaves correctly whereas other quarter deforms too much and throwing the following errors.

***ERROR: Facet 18824 between nodes 1556, 12426, 1557, and 1556 of instance
RUBBER-1-1 on surface ASSEMBLY_RUBBER-SURF has very small area.
Please check the mesh on this surface.

***ERROR: Excessive distortion of element number 263810 of instance RUBBER-1-1

Could you please help me to fix the error. I have checked the rubber elements and found no small elements or surfaces.

Best Regards,

Kamaraj Nadesan
