KSUM
Calculates and prints geometry statistics of the selected keypoints.
Calculates and prints geometry statistics (centroid location, moments of inertia, etc.) associated with the selected keypoints. Geometry items are reported in the global Cartesian coordinate system. A unit density is assumed, irrespective of any material associations [KATT, MAT]. Items calculated by KSUM and later retrieved by a *GET or *VGET command are valid only if the model is not modified after the KSUM command is issued.
