This quality parameter calculates the line length of line elements, the area of surface elements, and the volume of volume elements, with evaluation at Gauss points (4th order). It is implemented for all supported element types, including quadratic element types.
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.
