Optional parameters

ORIENTATION

Set this parameter equal to the name given to the ORIENTATION definition (Orientations) that specifies the orientation of the local system for rigid body degrees of freedom.

Optional, mutually exclusive parameters

FIXED

Include this parameter (default) to indicate that the inertia relief load from a previous step should remain fixed at its value from the beginning of the current step.

REMOVE

Include this parameter to indicate that the inertia relief load from a previous step should be removed in the current step.

Optional data lines to specify global (or local, if the ORIENTATION parameter is used) degrees of freedom that define the free directions along which inertia relief loads are applied

First line

  1. Integer list of degrees of freedom identifying the free directions.

Second line (only needed to define a reference point for the rigid body direction vectors when the user-chosen combination of free directions requires such a point)

  1. Global X-coordinate of the reference point.

  2. Global Y-coordinate of the reference point.

  3. Global Z-coordinate of the reference point.

These data lines are needed only if rigid body motions are constrained in some directions.

There are no data lines when the FIXED or REMOVE parameters are specified
