CASECC Table of Case Control command images.
TRL Transient response list.
NLFT Nonlinear Forcing function table.
DIT Table of TABLEij Bulk Data entry images.
KXX Stiffness matrix in any set. Usually h- or d-set.
BXX Viscous damping in any set. Usually h- or d-set.
MXX Mass matrix in any set. Usually h- or d-set.
PXT Transient response load matrix in h-set (modal) or d-set.
DSPT1 Design sensitivity processing table.
SILD Scalar index list for the p-set. Required for maximum efficiency during
symmetric decomposition and if KXX represents the d-set or a subset
of the d-set (SETNAME='D').
USETD Degree-of-freedom set membership table for the p-set. Required for
maximum efficiency during symmetric decomposition and if KXX
represents the d-set or a subset of the d-set (SETNAME='D').
PARTVEC Partitioning vector with values of 1.0 at the rows corresponding to
degrees of freedom which were eliminated in the partition to obtain
KXX, etc. Required for maximum efficiency during symmetric
decomposition and if KXX represents a subset of the d-set
(SETNAME='D'). PARTVEC is not required if KXX represents the hset.
See SETNAME parameter description below.
