This computes the volume of individual elements.
Note: This diagnostic does not consider degenerate hex elements, and will assign a negative value for them. The Volume/Area/Length check can be used for degenerate hex elements instead.
Note: The Volume and Volume/Area/Length criteria essentially use the same calculation for most element types and orders (linear or quadratic), but the volume check is optimized for 8–noded (linear) hex elements. It is recommended that Volume/Area/Length be used unless you want to check only the volume mesh, or you have a linear hex mesh. In these cases, the Volume check would be faster.
