| Foam::patchToPatches::inverseDistance | |
| Description | |
| Class to generate patchToPatch coupling geometry. Couples a face to the | |
| opposite face onto which its centre-normal ray projects, plus the immediate | |
| neighbours to that opposite face. The proportion of contribution from the | |
| different faces is calculated using inverse distance weighting. | |
