Class
Foam::AMIInterpolation
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.
