+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.
