Detailed Description

Interpolation class dealing with transfer of data between two primitive patches with an arbitrary mesh interface (AMI).

Based on the algorithm given in:

Conservative interpolation between volume meshes by local Galerkin projection, Farrell PE and Maddison JR, 2011, Comput. Methods Appl. Mech Engrg, Volume 200, Issues 1-4, pp 89-100

Interpolation requires that the two patches should have opposite orientations (opposite normals). The 'reverseTarget' flag can be used to reverse the orientation of the target patch.
