Fixed constraints
Pre/Post provides these commands for creating fixed constraints:
Fixed Constraint fixes all six degrees of freedom (DOF).
Fixed Translation Constraint fixes the three translational DOF. All rotational DOF are free.
Fixed Rotation Constraint fixes the three rotational DOF. All translational DOF are free.
For information about fixed constraints in the Simcenter Samcef environment, see Fixed constraint (Simcenter Samcef).
