I've got a bearing contact surface with 10mm wide cylinder of 13mm radius against a flat surface. (Assume steel on steel for starters.) I'm getting no where near what the theoretical Hertzian stresses should be in a real model I'm working on. When I run a simplified model and get the mesh down to the order of 1 mm then the stresses are about what they should be (~112ksi) (Yes, I know I'm mixing units but that's not the problem.)
When I run the same on a full model I get totally unrealistic numbers on the order of 10-50 ksi depending on the mesh size. When I use local volumes at 1 mm mesh size I end up with about 25ksi. Still totally unrealistic. Linear Static gives bigger numbers than the non-linear static.
