  This case deals with the free-convection flow arising in an
  annular cavity the inner cylinder of which is at a constant
  temperature higher than that of the outer cylinder.
  Buoyancy forces are activated via the exemplary subroutine GREX
  with setting of constants so as to activate the Boussinesq
  approximation.
         TEMPERATURE OF THE INNER CYLINDER ----- THOT
         TEMPERATURE OF THE OUTER CYLINDER ----- TCOLD
         THERMAL EXPANSION COEFFICIENT --------- BETA
