Detailed Description

Base class for patch-based injection models.

Class handles injecting at a random point adjacent to the patch faces to provide a more stochastic 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.
