fem_mod_elem_reverse	()

#  Purpose          :  This file provides an example of a call to the

#                      function fem_mod_elem_reverse()

#                      This file creates a surface and meshes it. It

#                      modifies the connectivity (reverses) of a

#                      particular element. Before and after this

#                      activity it gets the connectivity of that

#                      element to show the effect.

#                      This file can be run by starting a session of

#                      Patran, and running this session file

#                      menus on the menu bar.
