hello,
using ansys fluent to calculate lift and drag on subsonic wing

when i use the reference value option in the ANSYS, I am getting different lift and drag coefficients but the lift and drag value are the same..

when selecting the reference value option,i have selected compute from inlet in the drop down menu inside the option.


i would like to know the reason behind this variation.

I have posted the images which are last of total 500 iterations with and without selecting the reference values (option in ansys)

thank you
