| Class | |
| Foam::patchToPatches::intersection | |
| Description | |
| Class to generate patchToPatch coupling geometry. Coupling is determined by | |
| means of comparing the bound boxes generated by the intersection method. | |
| This generates an outer "envelope" of possible intersections that can be | |
| used for ray shooting and Lagrangian transfer. | |
| Note that this method is not added to the run-time selection table, as it | |
| is not a method which facilitates patch coupling or mapping. | |
