Velocity magnitude distribution not showing properly

Hey guys, whenever I plot the velocity distribution on this wing’s surface, all points are equal to zero. I do know that the velocity magnitude is null in the very first layer of the boundary layer, but I would like to get the velocity of the first layer adjacent to the boundary layer, so that I can see the effects of the wing on the fluid. If anyone knows how to solve this, it would help me a lot.
