25  Foam::CorrectPhi
26 
27 Description
28  Flux correction functions to ensure continuity.
29 
30  Required during start-up, restart, mesh-motion etc. when non-conservative
31  fluxes may adversely affect the prediction-part of the solution algorithm
32  (the part before the first pressure solution which would ensure continuity).
33  This is particularly important for VoF and other multi-phase solver in
34  which non-conservative fluxes cause unboundedness of the phase-fraction.
