BoundarySegmentΒΆ

Type:section

This allows to defined boundary treatment on edges of the geometrical primitive. Boundary treatment has to be stated on all edges of primitives which are also edges of the computational domain. In most cases it is advised to define the computational domain using a primitive (typically a Polygon) with the specific Priority Priority=-1. The boundary conditions attributed to the BoundarySegments of this primitive will be inherited to all boundaries of overlapping geometrical primitives. Therefore in this case it is sufficient to define boundary conditions to only this primitive.
