Equivalence Action

This section contains examples of some of the functions used to reduce all of the finite element model nodes that coexist at a point in the model space to a single node.


fem_equiv_all_group	()

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

#                      function fem_equiv_all_group()

#                      This session file creates a new database by the

#                      name new.db. Two curves are created and meshed.

#                      This function is then called to reduce all the

#                      nodes that coexist at single points to single

#                      nodes.

#                      This file can be run by starting a session of
