Description
    Solver for N incompressible, non-isothermal immiscible fluids with
    phase-change.  Uses a VOF (volume of fluid) phase-fraction based interface
    capturing approach.

    The momentum, energy 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.
