  This 1D transient case is based on the numerical benchmark test
  documented by Hewitt et al ( see Test 2.4, Sedimentation, in
  Multiphase Science and Technology, Vol.3, Ed. G.F.Hewitt et al,
  Hemisphere Pub. Corp., p474, [1987] ). Denser fluid initially
  rests above lighter fluid in a vertical tank, and then it falls
  down under gravity whilst the lighter fluid rises to the top.
  Eventually, after about 10s, all of the dense phase will rest on
  the bottom with the lighter phase at the top. The densities of the
  two fluids are chosen so as to be nearly equal (rhod=1 and rhol=
  0.999), and gravity is defined by g=0.5*(rhod+rhol)/(rhod-rhol),
  thus allowing comparison with the analytical and numerical
  solutions reported by Hewitt et al [1987]. The task is to predict
  the dense-phase volume-fraction profiles at t=2, 4, 6 and 8s. The
  PHOENICS predictions give reasonable agreement with analytical
  solution, despite the extremely coarse grid and time-step sizes.
