WARNING [4011]: SYSTEM MASS IS DIRECTIONAL. USING AVERAGED MASS CENTER AS MODAL FACTOR REFERENCE

Cause

This warning is generated when the system mass retains the directionality (when masses are different in X-, Y- and Z-directions) and the modal participation factors are calculated with respect to the centers of gravity.  In this case, the average mass of the 3 directions is used since the locations of the centers of gravity are different in different directions.

Analysis Type

Mode-based analysis (Eigenvalue analysis)
