Class
    Foam::PatchInjectionBase
 
Description
    Base class for patch-based injection models.
 
    Class handles injecting at a random point adjacent to the patch faces to
    provide a more stochsatic view of the injection process.  Patch faces are
    triangulated, and area fractions accumulated.  The fractional areas are
    then applied to determine across which face a parcel is to be injected.
