Here is my issue I have created a wind tunnel with spires in it using Gambit and meshed it. I have imported that into Fluent, I want to know how can see the bounday layer or some sort of a plot between Bounday layer and position or atleast anything related to the Boundary layer. I will be very much grateful if some one could help me in some way . Thanks Neelima

Although I have not properly understood your issue. But probably you have to make surface or line near the wall and plot the velocity vs grid-x (or grid-y)on that line or surface to get information about the boundary layer.
