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 unsteady turbulent flow. I could not find amoung the boundary conditions any condition that will satisfy u=0, v=constant except for inlet. 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

But you could still use inlet condition with negative velocity right!!!!!!!!!!

Why you want to make you life complicate using UDF..!!!!
