Overlapping cellZones in snappyHexMesh
 
I have a question about mesh generation with snappyHexMesh when there are multiple regions with mutual volume. I have generated concentric cylinders as separate STL files to give different levels in each region. I have assigned each of them a cellZone, shown in the figure (otherwise they will be removed). But after mesh generation with SHM, only the cylindrical cellZone which includes all cell zones (the biggest one) exist in the cellZones file in polyMesh folder as well as paraview, and other cellZones/patches are not available. As an example, the green patch shown in the image is not available. Is there any way to maintain all cell zones?
