GRDPNT

Description	Type	Default
GRDPNT > -1 will cause the grid point weight generator to be executed. The default value (GRDPNT = -1) suppresses the computation and output of this data. GRDPNT specifies the identification number of the grid point to be used as a reference point. If GRDPNT = 0 or is not a defined grid point, the reference point is taken as the origin of the basic coordinate system. The following weight and balance information is output to the Model Results Output File following the execution of the grid point weight generator: Total mass Location of center of gravity Mass moment of inertia Reference point Rigid body mass matrix [MO] relative to the reference point in the basic coordinate system Transformation matrix [S] from the basic coordinate system to principal mass axes Principal masses (mass) and associated centers of gravity (X-C.G., Y-C.G., Z-C.G.) Inertia matrix I(S) about the center of gravity relative to the principal mass axes Principal inertias I(Q) about the center of gravity Transformation matrix [Q] between S-axes and Q-axes. The columns of [Q] are the unit direction vectors for the corresponding principal inertias	Integer	-1
