  DISPLAY
  A two-dimensional square cavity is formed between two
  vertical walls, one of which is heated and the other cooled.
  the top and bottom of the cavity are bounded by walls at which
  there is friction but no heat transfer.

  The left wall is the hot wall of a temperature  Thot=1 K
  The right wall is the cold wall of a temperature Tcold=0 K

  ENDDIS
  DISPLAY
  Parameters:
  -----------

  1) The flow characteristics are set by way of
     Length of the cavity=CAVL
     Prandtl Number=Pr=enul/diffusity
     Rayleigh Number=Ra=Beta*g*(Th-Tc)/(enul*alfa)

     The Thermal Expansion Coefficient Beta as well as
     the Thermal diffusivity Alfa remain constant.

  2) This library case also enables the user to select
     the numerical solution procedure, namely:
    -the choice between two solvers:
     STONE or CNGR (Conjugate-residuals gradient)
    -the possibilty of the activation of EXPERT
     the Self-Adjusting-Relaxation Algorithm.

  ENDDIS

      expsol f .... expert is not used in the solver
      expdtf t .... expert is used to adjust false time step
      indtf 2   ... adjust the false time step of all velocities

      ifrsts 20 ... first adjustment sweep
      ifrequ 10 ... adjustments will be made every ifrequ sweeps
      facdec 0.5 .. decreases will be by a factor of facdec
