Direct Input Mass Matrix Selection
Description: Selects a direct input mass matrix.
Format:
M2PP = name
Example:
M2PP = MDMIG
| Option | Definition | Type |
|---|---|---|
| name | Name of the
 matrix that is defined on the
DMIG Bulk Data entry.
|
Character |
Remarks:
- Direct input matrices will not be used unless selected.
- Terms are added to the global stiffness matrix after constraints are applied.
- The matrix must be square or symmetric in form (field 4 on DMIG Bulk Data entry must contain the integer 1 or 6).
- M2PP input is not affected by PARAM, WTMASS. M2PP input must be in consistent mass units.
- This command is only supported in complex eigenvalue solutions.
