I am using utility skin solid elements which suppose to create shells with normals pointing outside solids. I noticed that for some solid meshes, produced skin has mixed normals. Is there a utility which can fix normals to point out without user interaction/inspection?
a more serious problem is that a lot of the elements are inside out, these are failing the positive volume connectivity test and they are giving rise to shell elements that point the opposite way to what you expect if the hex had a positive volume.
