RigidLink command

This command is used to construct a single MP_Constraint object.

rigidLink $type $masterNodeTag $slaveNodeTag

---

$type	string-based argument for rigid-link type:
	rod only the translational degree-of-freedom will be constrained to be exactly the same as those at the master node
	beam both the translational and rotational degrees of freedom are constrained.
$masterNodeTag	integer tag identifying the master node
$slaveNodeTag	integer tag identifying the slave node

NOTE: The constraint object constructed for the beam option assumes small rotations

EXAMPLE:

rigidLink beam 2 3; # connect node 3 to node 2 via a rigid link-beam.
