How to determine how many elements lie along a polygon edge?
In the context of either a '.fem' or a '.sim' file, within the 'simulation navigator' select the item 'groups', then:
* rhmb (mb3), new group
* set 'method = related elements'
* set 'selection filter = polygon edge'
* select the polygon edge(s) of interest - the elements related to the chosen polygon edge(s) will be selected and highlighted on the screen - the number of selected elements will be displayed in 'select object' portion of the 'new group' form
