fem_delete_elem_and_node	()

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

#                      function fem_delete_elem_and_node()

#                      This file opens a new database, and creates

#                      a surface. It meshes the surface and deletes

#                      one element and its associated nodes.

#                      This file can be run by starting a session of

#                      Patran, through the "File","Session",

#                      "Play" pulldown menus on the menu bar.

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

#                      function fem_delete_mesh_from_solid()

#                      This file opens a new database "new.db",

#                      creates a solid and meshes it. Then deletes

#                      the mesh from solid using the function.

#                      This file can be run by starting a session of

#                      Patran, through the "File","Session",

#                      "Play" pulldown menus on the menu bar.

#  The function fem_delete_mesh_from_solid()

#  has the following arguments:

#  fem_delete_mesh_from_solid

#     (  solid_select,

#        deleted_mesh,

#        not_found_mesh )
