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.
