Orthogonalization of discrete coordinates

Description

Title of program: RECT Catalogue Id: AAQW_v1_0 Nature of problem A two-dimensional boundary fitted orthogonal coordinate mesh may be required initially in an Eulerian calculation or at each time step in a semi-Lagrangian or waterbag code. A procedure for orthogonalizing a non-orthogonal coordinate mesh is described which preserves one set of coordinates. The preserved coordinate lines may be open or closed.
