Interpolation of cell-based displacements to the points with additional correction of patch-adjacent cells.
Snappy meshes often have moderately non-orthogonal faces next to patches. If these partches are moved, these already quite distorted faces quickly violate the quality criteria.
This method corrects patch-adjacent cells are by calculating the average translation, rotation and expansion of points connected to the patch. This transformation is then applied to all the points in the cell that are not on the patch. This does a better job of preserving the cell shape on the patch than pure interpolation, though it can simply move the problem into the next layer of cells.
The user needs only to specify the patches on which this correction is performed:
interpolation patchTransformed (movingPatch1 movingPatch2);
Note that this method is not defined for scalar displacement fields.
