Default wall suction

Dear All, I am trying to implement a constant wall suction boundary condition with a velocity of v=-0.001 m/s in a simple 2d channel geometry and steady state. I could not find amoung the boundary conditions any condition that will satisfy u=0, v=constant except for inlet. When I used inlet it did not satisfy the no slip condition! I guess I have to use UDF for this purpose! Can any one help me with this UDF as I am very new to UDF and how to compile it. Thanks
