M2PP

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:

  1. Direct input matrices will not be used unless selected.
  2. Terms are added to the global stiffness matrix after constraints are applied.
  3. The matrix must be square or symmetric in form (field 4 on DMIG Bulk Data entry must contain the integer 1 or 6).
  4. M2PP input is not affected by PARAM, WTMASS. M2PP input must be in consistent mass units.
  5. This command is only supported in complex eigenvalue solutions.
