hmtoggle_plus1Comments
1.The master (primary) and slave nodes must have non-zero mass and inertia.
2.The master (primary) node is not moved to the center of gravity of the body.
3.All nodes are equivalent (no distinction between master and slave nodes in this formulation) and may have other kinematical conditions of Lagrange Multiplier type.
