The meshing is done with stl imports and snappyHexMesh. I am in generall quite happy with the result, however after splitting the mesh. The patches are not correctly added to the regions and the patches, that surround the regions and are not part of the interfaces still show up in the neighbouring regions. The number of faces is quite low, so i think something is not as precise set as it should be. Considering the fact the the regions interfere with each other, an approach with topoSet and boxToCell proved to be wrong. I also varied the tolerance of the snapping process with no real progress. Any help/hints are greatly appreciated!
