BOUNDARY DISPLAY
This function allows the user to check the boundary of displayed part(s). It is used to check the proper connection between 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. See Figure 5.6.3.
