Henry Weller ffdb211bdc solvers::incompressibleMultiphaseVoF: New solver module for multiphase VoF simulations
executed with foamRun for single region simulations of foamMultiRun for
multi-region simulations.  Replaces multiphaseInterFoam and all the
corresponding tutorials have been updated and moved to
tutorials/modules/incompressibleMultiphaseVoF.

incompressibleMultiphaseVoF is derived from the multiphaseVoFSolver which adds
multiphase capability to the VoFSolver base-class used as the basis of all
two-phase and multiphase VoF solvers.

Class
    Foam::solvers::incompressibleMultiphaseVoF

Description
    Solver module for the solution of multiple incompressible, 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.

    A mixture approach for momentum transport is provided in which a single
    laminar, RAS or LES model is selected to model the momentum stress.

    Uses the flexible PIMPLE (PISO-SIMPLE) solution for time-resolved and
    pseudo-transient and steady simulations.
