OOF2: The Manual
Name
SegmentSide — The side of an element edge on which output data should be computed.
Description
SegmentSide selects the left or right side of
an Element Segment when evaluating Outputs on a
SkeletonEdgeBoundaryDomain.
When evaluating an Output along
a Segment separating two Elements, the result may depend upon whether
the evaluation point is considered to be in one Element or the other,
because Fields and Fluxes may be discontinuous at the boundary.
Skeleton edge
boundaries are directed, having a beginning and an end, so
it's possible to specify which Element to use for the evaluation by
choosing the one on the left or right side of the boundary.
“Left” means “On the left if you were on the
boundary and facing towards its end.”
If a boundary is external and only has an Element on one side, that
element will be used regardless of the
SegmentSide selected.
