This function allows the user to check the boundary of displayed part(s).  It is used to check the connectivity of elements.

eta/DYNAFORM highlights the free edges along a single surface.  For example, if three plate elements share a common edge, the common edge will be displayed as a boundary. An illustration is shown in Figure 5.5.4.
