Hi,

For a test-case, I was hoping to do the following:

- Deform an airfoil, using a sum of multiple Hicks Henne deformations (SU2_DEF)
- Compute the direct and adjoint solution (SU2_CFD)
- Get the gradient of the drag with respect to the deformations (SU2_DOT)

So far, this seems to work for a single Hicks Henne deformation, when the .cfg file contains:

DV_KIND= HICKS_HENNE
DV_PARAM= [ 0 , 0.5 ]
DV_VALUE= 0.1

However, would it be possible to combine multiple deformations? I tried:

DV_KIND= HICKS_HENNE
DV_PARAM= [ [0,0.5] , [1,0.5] ]
DV_VALUE= [ 0.1 , 0.1 ]

but this doesn't seem to work.

Thank you very much for your help!

Hi jack1980,

the syntax is for multiple design variables is

DV_KIND=HICKS_HENNE, HICKS_HENNE, ...

DV_PARAM = (0.0, 0.05); (0.0, 0.1); ...

DV_VALUE= 0.5, 0.5, ....

Hi all,

I am trying out a similar test-case as Mr. Jouke. But in my case the only change being multiple FFD_CONTROL_POINT instead of HICKS_HENNE.

DV_KIND= FFD_CONTROL_POINT, FFD_CONTROL_POINT, ...
DV_PARAM= (SCB1, 0, 0, 0, 0, 0, 1); (SCB1, 0, 0, 1, 0, 0, 1); ..
DV_VALUE= 0.2, 0.2, 0.2, ..

But the syntax mentioned above doesn't seem to be working for me.

On running SU2_DOT_AD I am getting the the following error:
[localhost:07682] *** Process received signal ***
[localhost:07682] Signal: Segmentation fault (11)
[localhost:07682] Signal code: (128)

[localhost:07682] *** End of error message ***

I am using SU2 6.0.0 "Falcon".

Thank you very much for your help!
