.SH "NAME"
freefoam-combinePatchFaces \- Checks for multiple patch faces on same cell and combines them\&.
.SH "SYNOPSIS"
.sp
\fBfreefoam combinePatchFaces\fR \fI<feature angle [0\&.\&.180]>\fR [\-concaveAngle \fI<angle [0\&.\&.180]>\fR] [\-help] [\-srcDoc] [\-doc] [\-overwrite] [\-parallel] [\-case \fI<dir>\fR] [\-snapMesh]
.SH "DESCRIPTION"
.sp
These result from e\&.g\&. refined neighbouring cells getting removed, leaving 4 exposed faces with same owner\&.
.sp
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
.sp
E\&.g\&. to allow all faces on same patch to be merged:
