This Subcases dependant form allows you to select the defined Nonstructural Mass sets. The Defined NSM Sets box lists all defined Nonstructural Mass property sets. Since it is possible to have up to four property sets with the same set name, the Distributed vs Lumped and Element vs Property attributes of the sets are listed in columns to the left of the property set name.

Individual groupings of Nonstructural Mass property sets can be selected in the form and then applied with the Apply button. By default, all of the listed Nonstructural Mass property sets are selected by the case control code even if they are not shown as selected in the Defined NSM Sets box.

Groups of Nonstructual Mass properties can be excluded from an analysis by not including that specific subcase in the analysis job. Individual Nonstructural Mass properties can be excluded from an analysis by setting the applied mass for that property set to zero (0).

This subform appears when the Select NSM Properties... button is selected from the Subcases form.
