Class
    Foam::pressureDirectedInletOutletVelocityFvPatchVectorField

Description
    Velocity inlet/outlet boundary condition for pressure boundary 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 flux with
    the specified `inletDirection'.
