-Description
-    Solver for two compressible, non-isothermal immiscible fluids using a VOF
-    (volume of fluid) phase-fraction based interface capturing approach,
-    with optional mesh motion and mesh topology changes including adaptive
-    re-meshing.
-
-    The momentum and other fluid properties are of the "mixture" and a single
-    momentum equation is solved.
-
-    Turbulence modelling is generic, i.e. laminar, RAS or LES may be selected.
