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

  ENUL=1.0 for setting one-dimensional flow.

  PHOTON USE commands are included to assist display of results.
