*CONSTRAINED_JOINT_REVOLUTE
\$
\$  Create a revolute joint between two rigid bodies.  The rigid bodies must
\$  share a common edge to define the joint along.  This edge, however, must
\$  not have the nodes merged together.  Rigid bodies A and B will rotate
\$  relative to each other along the axis defined by the common edge.
\$
\$  Nodes 1 and 2 are on rigid body A and coincide with nodes 9 and 10
\$  on rigid body B, respectively.  (This defines the axis of rotation.)
\$
\$  The relative penalty stiffness on the revolute joint is to be 1.0,
\$  the joint is well lubricated, thus no damping at the joint is supplied.

\$\$\$\$\$\$\$\$\$\$\$\$  Define a joint stiffness for the revolute joint described above.
\$
\$  Attributes of the joint stiffness:
\$    - Used for defining a stop angle of 30 degrees rotation
\$        (i.e., the joint allows a positive rotation of 30 degrees and
\$           then imparts an elastic stiffness to prevent futher rotation)
\$    - Define between rigid body A (part 1) and rigid body B (part 2)
\$    - Define a local coordinate system along the revolute axis
\$        on rigid body A - nodes 1, 2 and 3 (cid = 5).  This is used to
\$        define the revolute angles phi (PH), theta (T), and psi (PS).
\$    - The elastic stiffness per unit radian for the stop angles
\$        are 100, 10, 10 for PH, T, and PS, respectively.
\$    - Values not specified are not used during the simulation.
