Class
    Foam::pressureInletVelocityFvPatchVectorField
 
Group
    grpInletBoundaryConditions
 
Description
    This velocity inlet boundary condition is applied to patches where the
    pressure is specified.  The inflow velocity is obtained from the flux with
    a direction normal to the patch faces.
 
Usage
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            pressureInletVelocity;
        phi             phi;
        rho             rho;
        value           uniform 0;
    }
    \endverbatim
 
Note
    If reverse flow is possible or expected use
    the pressureInletOutletVelocityFvPatchVectorField condition instead.
