Detailed Description

This boundary condition provides a velocity outlet boundary condition for patches where the pressure is specified. The outflow velocity is obtained by "zeroGradient" and then corrected from the flux:

\[ U_p = U_c - n (n \cdot U_c) + \frac{n \phi_p}{|S_f|} \]

where

\( U_p \) = velocity at the patch [m/s]
\( U_c \) = velocity in cells adjacent to the patch [m/s]
\( n \) = patch normal vectors
\( \phi_p \) = flux at the patch [m3/s or kg/s]
\( S_f \) = patch face area vectors [m2]

where

Property Description Required Default value
phi name of flux field no phi
rho name of density field no rho

Example of the boundary condition specification: 

    <patchName>
    {
        type            fluxCorrectedVelocity;
        phi             phi;
        rho             rho;
    }
Note
If reverse flow is possible or expected use the pressureInletOutletVelocity condition instead.
