combinePatchFaces - is the part of OpenFOAM - a free, open source CFD software.




combinePatchFaces is a Checks for multiple patch faces on same cell and combines them. These result from e.g. refined neighbouring cells getting removed, leaving 4 exposed faces with same owner. Rules for merging: only boundary faces (since multiple internal faces between two cells not allowed anyway) faces have to have same owner faces have to be connected via edge which are not features (so angle between them < FEATURE_ANGLE given in degrees [0-180])outside of faces has to be single loop outside of face should not be (or just slightly) concave (so angle between consecutive edges < concaveAngle)
