AUNITS $
AERO Table of control information for aerodynamic analysis.
CSTMA Table of aerodynamic coordinate system transformation matrices for
g-set + ks-set grid points.
BGPDT Basic grid point definition table.
USET Degree-of-freedom set membership table for g-set.
TRX Acceleration selection matrix for the list of aerodynamic extra-points
(6 rows by NX columns).
TR Matrix to transform forces from the support point to the aerodynamic
reference point.
PRBDOFS Partitioning matrix to partition the "active" URDDI from the "inactive".
Active URRDI are assigned a 1.0 value and are connected to the
SUPORT degrees-of-freedom.
URDDIDX An instance of an ADBINDX that describes the acceleration entries.
URDDUXV UX vector states for the active URDDi. These are rows of TRX that are
non-null. Null rows occur either because the USER didn't define
AESTAT, URDDi, OR because the associated URDDi is invalid for this
symmetry condition (e.g., URDD1,3,5 are invalid for antisymmetric
analysis).
TRANTR Transpose of TR where the number of columns of TR matches the
URDDUXV states of TRX. Both are reduced to just the active origin rigid
body degrees-of-freedom.
