no-slip problem
 
It's my first test of fluent but let me feel very frustated.

Firstly, I give the settings : geometry: a simple 2d channel left/right boundaries are velocity inlet/outlet flow bottom/top boundaries are wall Materials: water fluid

The problem is: when I set the wall as no-slip and viscous->laminar, I can't find the simulated velocity field has gradient in the normal direction of the wall, and he velocity at boundaries are not zero. The result is nearly the same when I set viscous to "inviside"

Why?

Thanks in advance.
