A2GG

Subcase Information Entry

A2GG - Direct Input Fluid-Structure Coupling Matrix Selection

Description

The A2GG command can be used in the Subcase Information section to select a direct input fluid-structure coupling matrix.

Format

A2GG = name

Argument	Description
name	Name of a fluid-structure coupling matrix that is input in the bulk data section using the DMIG card.

1.	DMIG matrices will not be used unless selected in the Subcase Information section.

2.	The matrix selected applies to all subcases.

3.	The selected fluid-structure coupling matrix is always added to the computed coupling matrix.

4.	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.

5.	Multiple instances of A2GG are not allowed, and will result in an error termination.
