Hi,
I have been trying to simulate the flow over a rectangular cylinder but I still couldn't get the CD close to the results published on paper. I used k-epsilon method to obtain a steady state results before using LES to find the unsteady state.

Boundary Condition :-
Inlet Velocity : 0.32 m/s
Turbulent Intensity : 4.58%
Turbulent Length : 0.07 m

Reynolds Number is 22000

My drag Coefficient is approximately 1.4~1.6 and the CD published on paper was 2.0~2.2.

I attached my fluent mesh file which I uploaded on Megaupload and hope that someone can identifies my mistakes. Thanks in advance
