fluent bad lift coefficient

hi everyone
I'm modeling water flow around a 2d rectangular cylinder. I managed to get a good agreement with the experimental results for the drag coefficients but the lift coefficient differs alot. Is there a way to correct this?
thanks

I am trying to do similar thing. I had a few questions if you don't mind answering:

1. Whats your Re ?
2. What turbulent model are you using?

I am dealing with circular cylinder and using K-W and SST as the turbulence model. My drag values are predicted correctly but not the lift values.

Thanks
