  A wide thin box moves diagonally across a two-dimensional space
  at uniform velocity. A box is an InForm-made object.
  The domain contains a porous medium causing resistance to flow.
  The boundaries of the domain are open.
  The fluid is slightly compressible.

  Parameters are provided which enable the effects on convergence
  and accuracy to be noted of:
  * box size divided by cell size;
  * time to traverse a cell divided by time step;
  * the compressibility factor;
  * the resistance coefficient;
  * pressure-drop coefficients at the ends of the domain.

  PHOTON USE commands are included to assist display of results.
