Adjoint solver wing twist optimization!!

mechesanjiv · August 15, 2015, 07:32

Hello all,
I am quite stuck in the adjoint solver. Is it possible to optimize the twist of a wing without changing the camber and chord for the airfoil while doing 3d wing optimization in adjoint solver?

Any ideas would be appreciable!!

Thanks,

You can define the wing model without changing camber or chord and apply a twist to the profile. You can even map the adjoint solution to the parametric model (the latter is only available in the commercial version). If you are a student you can get a full license that allows that, too.

Hi dear friend,
I have the same problem. Did you manage to keep the airfoil chord and camber fixed and unchanged while optimizing ?

Hi dear friend,
I have the same problem.
Can you help me how to keep the chord of a 3D wing fixed and unchanged while doing optimization with Fluent's adjoint solver ?

Thanks in advance.
Regards.

HI there,

Here is an example of a parametric wing in CAESES that allows to change the angle of the wing along the span and keeps the same chord and camber.

Cheers
Claus

PS: if you want to have the project file for CAESES, get in touch with me via contact form on our website, please.

In what software was this project done ? I use the Fluent software and its additional Adjoint solver for optimization.
I don't have your website address, how and where can I send you a message ?

It is done in CAESES, see www.caeses.com

At the bottom of the page you can find the "contact us"
