  A 2-phase turbulent mixture flows over a backward-facing step of
  height h in a 2D channel of exit width 3h. The calculation starts
  at x = -4h and terminates at x = 16h, where a fixed-pressure
  boundary condition is applied. The Reynolds number based on the
  step height is 45,000 and uniform profiles of u, k and e are
  specified at the inlet to the calculation domain. The density
  ratio of the fluids is 100:1 .
