-Element Diameter 3D
-*******************
-
-This quality control criterion consists in calculation of the maximal length of edges and diagonals of 3D mesh elements (tetrahedrons, pyramids, etc). For polyhedra the value is always zero.
-
-*To apply the Element Diameter 3D quality criterion to your mesh:*
