  28 Description
  29     Solver for 2 incompressible, isothermal immiscible fluids using a VOF
  30     (volume of fluid) phase-fraction based interface capturing approach.
  31
  32     The momentum and other fluid properties are of the "mixture" and a single
  33     momentum equation is solved.
  34
  35     Turbulence modelling is generic, i.e.  laminar, RAS or LES may be selected.
  36
  37     For a two-fluid approach see twoPhaseEulerFoam.
