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.
