| Class | |
| Foam::fvRegionSplit | |
| Description | |
| This class enumerates disconnected regions of an fvMesh. It inherits a | |
| label list which it populates on construction with the region index for | |
| each cell in the mesh. | |
| Optionally additional faces can be blocked by providing a scalar field and | |
| value. A face is then considered blocked if the values in the adjacent | |
| cells (including via coupled boundaries) span the given value. | |
