Class
    Foam::solvers::multiphaseVoFSolver
 
Description
    Base solver module for the solution of multiple 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.
 
    Uses the flexible PIMPLE (PISO-SIMPLE) solution for time-resolved and
    pseudo-transient and steady simulations.
