   This case simulates the natural convection phenomena which occur
   when passive solids are placed in stably  stratified  fluids  of
   different  thermal conductivities.  Because of highly non-linear
   problem nature   the  number  of  sweeps  for  under-relaxations
   employed may not be enough for  completely  converged  solution.
   More details  of physical nature and mathematical statement plus
   the experimental and numeric data for comparisons can  be  found
   in  G.L.Quarini and K.H.  Winters ( Proc.  of 1st U.K.  National
   Conference on Heat Transfer, 1984, v.2, pp. 857-866)
