I am conducting a fluid flow problem in a tube. I wanna define a wall slip boundary condition by specifying a constant wall shear stress. I have successfully get the solution under no-slip boundary. But I don't know how to implement wall slip boundary conditions. There does exist a slip option under Physics-->boundary settings-->Boundary type:wall-->Boundary condition:slip. However, where can I define the slip velocity or wall shear stress?

Is there anybody can give me an example about wall slip boundary conditions, I can only find non-slip boundary conditions examples. Thank you.
