Surface normal vector error

Question asked by Derek Bishop on Jul 19, 2009

I was doing an FEA study recently and found that the in some cases I got a message saying there was an error trying to find a surface normal vector. It mainly seemed to be an issue when running in large displacement mode with curvature based meshes. The model comprised solids and shells. I had to use curvature based meshing because the standard quality meshing kept failing. Has anyone else had problems with this? I have also sent through an RX on this matter.
