\$  LSTC Example
\$
\$
\$  Five different contacts are defined for the same problem.  The only one
\$  active is type 3, surface to surface.  The other four are commented out.
\$  To switch contact types, comment out the active one and remove the comments
\$  from the desired one.
\$
\$  Units: mm, s
