Dear all,


I am trying to optimize an A320 aircraft wing. Could someone please tell me how can I change the wing sweep angle in SU2?


I have gone through all the SU2 tutorial but could not find a way to change the wing sweep angle. It would be really helpful if someone could help me out here.


Thanks in advance

Dear Shreyas,
SU2 is a solver and needs a mesh (2D or 3D). Wing geometric parameters like Sweep, Aspect Ratio, Taper ration, Twist and airfoil cross sections need to be incorporated in a CAD file. This CAD file then needs to be imported into a Mesh generation file to obtain a 3D volume mesh in .SU2 format. SU2 solver reads the mesh file for further processing. So SU2 Config includes other parameters for computing like M, AOA, bets, turbulence model ( or Euler) and whole lot of others. SO you want to change geometry , you have to work at the CAD level.You can explore OpenVSP tool for this purpose, I use GMSH, of course both are open source. Check out the web site "JoshtheEngineer" he has nice videos to explaining geometry, mesh creation for SU2.
Hope it helps.

Dear Mr. Narahari,


Thank you very much for your reply.



Sorry, I guess my query was not clear as I had not included all the details of my problem.



Actually, I have already created a 3D mesh and converted it into .SU2 format and placed a FFD box enclosing my wing. I have also verified the SU2 gradients by performing sensitivity analysis. Now while running my optimization I need to define wing sweep angle as a design variable. I would like to know how this can be done in SU2?



I hope my query is clear now. If you need additional details, kindly let me know.


Thanks and kind regards

Hi Shreyas,

I am really interested in changing sweep angle by using mesh deformation. I used FFD box and move all outer corners through x direction but it doesnt help much to me.

If you find anythig, please let us know.

Thanks,

Kaan
