Comments
            - Refer to Non-structural Mass in the User Guide
                for more information on the use of this card.
 
            - Non-structural mass in this format must be
                    selected by the NSM (Subcase Information Entry) Subcase
                    Information selector.
 
            - No S# may be the
                identification number of a non-structural mass set defined by another
                    NSMADD entry.
 
            - NSMADD entries take
                precedence over NSM, NSML,
                    NSM1 or NSML1 entries. If both have the
                same SID, only the NSMADD entry will be
                used.
 
            - The value of the non-structural mass does
                    not change during Topology Optimization.
