Hi Everyone,
I am performing airfoil Pitching in fluent using UDF. I am using this equation

alpha = alpha(o)+alpha(a)*sin(Wt)
alpha(o) = mean angle of attack (10)
alpha(a) = pitching amplitude (15)

My problem however is how to plot the lift coefficient vs AOA as shown in the picture below. Normally in the static case, you specify the angle of attack for x and y in fluent and report the forces after simulation for each angle of attack. Which means you have to run a lot of cases if your aoa is between (-5 to 25).

However looking at the pitching case and the picture I do not know to plot it. Please any help will be appreciated.

Regards
Franklyn
