How to specify Navier slip boundary condition

I am trying to simulate the pressure-driven flow in a straight slip-microchannel using COMSOL 3.5. I am not sure that my specified slip boundary condition is right, but the result is incorrect compared to the analytical solution. I specified the wall slip boundary condition as the sliding wall: Uw=-b*uy, where b is the slip length and uy is the velocity gradient at wall.
Is there anybody who has comments and suggestions on this issue?
Thank you.
Adrian
