Hello,

I would like to compute the gradient of lift and drag with respect to the angle of attack. I tried to simplify the config file, and came back to the NACA12 use case and set:

DV_KIND= ANGLE_OF_ATTACK
DV_MARKER= ( airfoil )
DV_PARAM= 1.
DV_VALUE= 10.0
DEFINITION_DV= (101, 1.0 | airfoil | 1.0)

But these seem to have no effect: the lift is null and the gradient of lift and drag with respect to the design variables is null too in of_grad_cd.csv and of_grad_cl.csv

When using SCREEN_OUTPUT= (SENS_AOA), I see it is computed somewhere but I cant get it in the gradient.

Is this doable?

Thanks
François
