Detailed Description

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)
• outside of faces has to be single loop
• outside of face should not be (or just slightly) concave (so angle between consecutive edges < concaveangle

E.g. to allow all faces on same patch to be merged:

combinePatchFaces .. cavity 180 -concaveAngle 90

Usage

• combinePatchFaces [OPTIONS] <feature angle [0..180]>

Parameters:

\<feature

angle [0..180]>
