It's been a long time, and I don't remember why, but I get different answers (13000 psi vs 21000 psi) when I change the default mesh size. In this case, the default mesh size is ~ 1/4 inch, but the analyzed part has some holes on the order of .125 inch. I have reduced the mesh to 5 times smaller to increase resolution, but do not have a good feel for accuracy at this level. Any rules of thumb for mesh size vs. part size, etc? Appreciate your help.
