Rigid sphere dropped onto a plate
\$
\$  LSTC Example
\$
\$
\$  * Part 2 - plate
\$      Shells (2.5 mm thick)
\$      Mild steel (with strain rate effect)
\$      Constrained on all four edges
\$      Connected using Tied Nodes with Failure Constraints
\$
\$  * Part 3 - sphere
\$      Solids
\$      Rigid
\$      Initial Velocity: -89 mm/ms to all nodes of the sphere
\$
\$  * Contact: nodes (plate - 2) to surface (sphere - 3)  good   <== this file
\$             nodes (sphere - 3) to surface (plate - 2)  bad
\$
\$  Note: For a really good demonstration of bad contact, remove all of the
\$        *CONSTRAINED_TIED_NODES_FAILURE at the end of the deck and re-run
\$        with the two contact definitions pointed out above.
\$
\$  Units: mm, kg, ms, kN, GPa, kN-mm
