createPatch deletes cellSets/cellZones
I have a simple porous media in a duct, and use insideCells to create a cellZoneSet, which is then turned into a cellZone by topoSet. checkMesh reports the number of cells and bounding box of this cellZone correctly.
However, after running createPatch -overwrite, the cellZone is empty. Is this desired behavior, or a bug?
I can create a very small test case is needed.
