Class
    Foam::pressureNormalInletOutletVelocityFvPatchVectorField
 
Description
    This velocity inlet/outlet boundary condition is applied to patches where
    the pressure is specified.  A zero-gradient condition is applied for
    outflow (as defined by the flux); for inflow, the velocity is obtained from
    the flux with a direction normal to the patch faces.
 
Usage
    \table
        Property     | Description             | Required    | Default value
        phi          | flux field name         | no          | phi
        rho          | density field name      | no          | rho
    \endtable
 
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        type            pressureNormalInletOutletVelocity;
        phi             phi;
        rho             rho;
        value           uniform 0;
    }
    \endverbatim
 
    Note:
        Sign conventions:
      - positive flux (out of domain): apply zero-gradient condition
      - negative flux (into of domain): derive from the flux and patch-normal
        direction
