  DISPLAY
   In this example we have a gas leak from a small breach in
   a pipe, within a large equipment room.  To "capture"  the
   scale of the  gas leak (of  the order of  1mm) within the
   large room (characteristic length 1m) is difficult to  do
   with a single  grid.  Here  a sequence of  4 successively
   embedded grids are used to resolve both the leak aperture
   itself and the resulting jet.

   The  gas  is  heavier  than  air,  and the model includes
   bouyancy effects.  A fixed turbulent viscosity based upon
   experimental results for the round turbulent jet has been
   used.

   NOTE !!! The size of F-array should be at least 2000000.
