NAME¶

freefoam-surfaceSplitNonManifolds - Takes multiply connected surface and tries to split surface at multiply connected edges by duplicating points.

SYNOPSIS¶

freefoam surfaceSplitNonManifolds <Foam surface file> <surface output file> [-case <dir>] [-srcDoc] [-debug] [-doc] [-help]

DESCRIPTION¶

Introduces concept of - borderEdge. Edge with 4 faces connected to it. - borderPoint. Point connected to exactly 2 borderEdges. - borderLine. Connected list of borderEdges. By duplicating borderPoints this will split borderLines. As a preprocessing step it can detect borderEdges without any borderPoints and explicitly split these triangles. The problems in this algorithm are: - determining which two (of the four) faces form a surface. Done by walking face-edge-face while keeping and edge or point on the borderEdge borderPoint. - determining the outwards pointing normal to be used to slightly offset the duplicated point. Uses sortedEdgeFaces quite a bit. Is tested on simple borderLines resulting from extracting a surface from a hex mesh. Will quite possibly go wrong on more complicated border lines (i.e. ones forming a loop). Dumps surface every so often since might take a long time to complete.
