Class
    Foam::pressureInletOutletVelocityFvPatchVectorField

Description
    Velocity inlet/outlet boundary condition patches for where the pressure is
    specified.  zero-gradient is applied for outflow (as defined by the flux)
    and for inflow the velocity is obtained from the patch-face normal
    component of the internal-cell value.
