Foam::fixedFluxPressureFvPatchScalarField
Description
Foam::fixedFluxPressureFvPatchScalarField
Adjusts the pressure gradient such that the flux on the boundary is that
specified by the velocity boundary condition.
The predicted flux to be compensated by the pressure gradient is evaluated
as (phi - phiHbyA), both of which are looked-up from the database as is
the pressure diffusivity Dp used to calculate the gradient.
The names of the phi, phiHbyA and Dp fields may be optionally specified.
