Class
    Foam::pressureDirectedInletVelocityFvPatchVectorField

Description
    Velocity inlet boundary condition for patches where the pressure is
    specified. The inflow velocity is obtained from the flux with the
    specified "inletDirection" direction.  If reverse flow is possible or
    expected use the "pressureDirectedInletOutletVelocityFvPatchVectorField"
    BC instead.
