Input Data Blocks:
GEOM1 Table of Bulk Data entry images related to geometry.
GEOM2 Table of Bulk Data entry images related to element connectivity and
scalar points.
GEOM4 Table of Bulk Data entry images related to constraints,
degree-of-freedom membership, and rigid element connectivity.
EPT Table of Bulk Data entry images related to element properties.
MATPOOL Table of Bulk Data entry images related to hydroelastic boundary, heat
transfer radiation, virtual mass, DMIG, and DMIAX entries. Required
for DMIG and virtual mass partitioning with domain solver
ACMS='YES'.
DYNAMIC Table of Bulk Data entry images related to dynamics. Grid points on
DPHASE, DELAY, TIC, and DAREA records will be assigned to the
residual structure if ACMS='YES'.
CASECC Table of Case Control command images. Required for MFLUID set
identification number.
MAT Matrix. Must be square and symmetric.
GPL External grid/scalar point identification number list.
USET Degree-of-freedom set membership table for g-set.
SIL Scalar index list.
