BEarea()

area of a boundary element

Computes the area of a boundary element of a fixed boundary, e.g. of a triangle. This is useful when used together with BEsum() in the context of MOVE statements or within a BE_MONITOR_ITEM or SAVE_BE_MONITOR_ITEM. Example:

begin_equation{$EqunName$} ... BEarea(1) ... end_equation

Note: BEarea() needs a dummy argument (in the example, 1). So far, its value is ignored.
