This command is used to construct a single MP_Constraint object.

rigidLink $type $rNodeTag $cNodeTag

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