Class
    Foam::CorrectPhi

Description
    Flux correction functions to ensure continuity.

    Required during start-up, restart, mesh-motion etc. when non-conservative
    fluxes may adversely affect the prediction-part of the solution algorithm
    (the part before the first pressure solution which would ensure continuity).
    This is particularly important for VoF and other multi-phase solver in
    which non-conservative fluxes cause unboundedness of the phase-fraction.
