A2GG
Subcase Information Entry The A2GG command can be used to select a direct input fluid-structure coupling matrix.
Format
A2GG = name
Definitions
| Argument | Description |
|---|---|
| name | Name of a fluid-structure coupling matrix that is input in the Bulk Data section using the DMIG card. |
Comments
- DMIG matrices will not be used unless selected in the Subcase Information section.
- The matrix selected applies to all subcases.
- The selected fluid-structure coupling matrix is always added to the computed coupling matrix.
- The referenced DMIG entry must be a square matrix (field 4 must be 1), where GJ corresponds to fluid points, CJ=0, Gi corresponds to structural points, Ci corresponds to DOF, and Ai corresponds to the area values.
- Multiple instances of A2GG are allowed, and the referenced matrices will used in the solution.
