Detailed Description

Interpolation of cell-based displacements to the points with additional correction for interpolation inconsistency on patches.

The default interpolation method interpolates from the cells to all points except those on boundaries with value boundary conditions. The discrepancy across the boundary cell can cause shearing and inversion if the cells are of very high aspect ratio.

This method applies the default interpolation to *all* points, including those on value boundaries. The difference between the interpolated value on the boundary and the desired boundary condition is then propagated into the mesh with a wave. Contributions from different patches are inverse-distance weighted, and the result is added to the default interpolation. The result of this is that thin boundary cells are maintained much more accurately for non-uniform patch displacements.

The user must specify the patch groups from which to propagate the motion. Ideally, these groups will be opposing; i.e. one group with the aerofoil, and one with the far field:

    interpolation patchCorrected
    (
        (aerofoilUpper aerofoilLower)
        (farField)
    );
