3 The coordinate locations (x, y, z) in BGPDT
converted to a matrix and translated by
XG:
where ux , uy , uz are the translations and
rotations of XG in the basic coordinate
system. BGPDT contains the location of
each grid point in the basic coordinate
system. COORID is ignored.
4 A six rows by g-column rigid body matrix
where each row represents the motion, in
the global coordinate system, of all grid
points due to the unit motion of the grid
point listed on PARAM,GRDPNT. Grid
point GRDPNT is given a unit translation
or rotation in each direction of the basic
coordinate system. XOUT represents the
rigid body modes of the structure with no
mechanisms. The motion is output in the
global coordinate system. XG and
COORID are ignored.
5 Same as IOPT=1.
6 A g-row by 6-column rigid body matrix
where each column represents the motion
of all grid points due to a unit motion of an
r-set degrees of freedom (see SUPORTi
Bulk Data entries).
