Aerofoil lift coefficient
 
Hi,
Does anybody understand how the OF libforces.so package actually works out the values of lift and drag coefficient?

I'll be more explicit; I'm comparing computational results to experiment and I'm getting a very good approximation for the lift coefficient but not a very good approximation to the pressure distribution on the aerofoil....

I can't understand how this is correct?

I thought it might be something to do with how OpenFOAM works out the actual lift coefficient but from what I understand, openfoam does indeed just integrate the pressure distribution.....

Does anybody have any experience with this and could they point me in the right direction?
