# NSM

Subcase Information Entry The NSM command can be used to select a non-structural mass set for mass generation.

NSM = option

## Example 1

In this example, NSM 12 is applied to the model for Subcase 1 and NSM 13 is applied to the model for Subcase 3. There is no non-structural mass applied to the model for Subcase 2:
SUBCASE 1
ANALYSIS=STATICS
SPC = 1
NSM=12

SUBCASE 2
ANALYSIS=STATICS
SPC = 3

SUBCASE 3
ANALYSIS=STATICS
SPC = 5
NSM=13

BEGIN BULK
NSM,12,PSOLID,3,0.3
NSM,13,PSOLID,3,0.7

## Example 2

In this example, NSM 12 is applied to the model for Subcase 1 and NSM 13 is applied to the model for Subcase 3. Since there is no NSM entry within Subcase 2, the global reference of NSM 14 is used.
NSM=14
SUBCASE 1
ANALYSIS=STATICS
SPC = 1
NSM=12

SUBCASE 2
ANALYSIS=STATICS
SPC = 3

SUBCASE 3
ANALYSIS=STATICS
SPC = 5
NSM=13

BEGIN BULK
NSM,12,PSOLID,3,0.3
NSM,13,PSOLID,3,0.7
NSM,14,PSOLID,3,0.5
