Thank's.

Ok i have an other idea. What about puting OPT_BOUND_LOWER from -0.1 to 0 ?! That shoud allow to only inscrease the yline.
In addition to OPT_CONTRAINT previously viewed.

But it's not only thickness because we can imagine a new airfoil design with exactly the same thickness which doesn't respect the constraint y>ybaseline (if the airfoil bends upwards with the same...

Yes i think that's it, for naca0012 airfoil, the baseline profil is ybaseline=+- 0.6*[0.2969*sqrt(x) - 0.1260*x - 0.3516*x2 + 0.2843*x3 - 0.1015*x4].
And i need to have, for all x (airfoil lenght)...

And the approach with THIKNESS in several x (0, 0.2, 0.4 etc.. , 1) is only coherent for symetric design so i can do better i think

Shape optimisation with constraint : NACA0012

Hi everebody,
I'm an absolut beginner in SU2, i have to optimise the shape of NACA0012 Airfoil. The probleme is the following :

- Objective : Cd(drag) minimisation.
- Constrainte : y>ybasline...
