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:

where

	=	velocity at the patch [m/s]
	=	velocity in cells adjacent to the patch [m/s]
	=	patch normal vectors
	=	flux at the patch [m3/s or kg/s]
	=	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.
