#include <meshTools/twoDPointCorrector.H>
Class applies a two-dimensional correction to mesh motion point field.
The correction guarantees that the mesh does not get twisted during motion and thus introduce a third dimension into a 2-D problem.
The operation is performed by looping through all edges approximately normal to the plane and enforcing their orthoginality onto the plane by adjusting points on their ends.
