  CONSERVATIVE LOW-DISPERSION ALGORITHM (CLDA) - flow at various
  angles 2-dimensional (x-y), Cartesian, steady/unsteady, elliptic
  simulation.This demonstration of the CLDA (conservative low-
  dispersion algorithm) concerns the flow of two fluids, "red"
  and "blue" in a 2D domain. Physical diffusion is absent, so that
  the apparent mixing is a consequence of numerical diffusion alone.

  The subroutine GXCLDA.F id used.

  Several different runs can be made, including a transient.
  If the transient is chosen, PHOTON-readable files P1, P2, etc
  will be created; but the PHOTON USE commands supplied at the top
  of this Q1 call in only that for the last time step. To see the
  others type p;P1 , P;P2, etc
