Hi,

I'm trying to perform the mesh deformation of Onera M6 mesh with SU2_DEF using multiple FFD control points based on the discussion here. The same mesh has been used in the current case as used in the tutorial of Onera M6. I have used the following lines of code in my config file-

% ------------------------ DESIGN VARIABLE PARAMETERS ------------------------%
%
% Kind of deformation (FFD_SETTING, FFD_CONTROL_POINT_2D, FFD_CAMBER_2D, FFD_THICKNESS_2D,
%                      HICKS_HENNE, PARABOLIC,
%                      NACA_4DIGITS, DISPLACEMENT, ROTATION, FFD_CONTROL_POINT, 
%                      FFD_NACELLE, FFD_TWIST, FFD_ROTATION,
%                      FFD_CAMBER, FFD_THICKNESS, SURFACE_FILE)
DV_KIND= FFD_CONTROL_POINT, FFD_CONTROL_POINT
%
% Marker of the surface in which we are going apply the shape deformation
DV_MARKER= ( UPPER_SIDE, LOWER_SIDE, TIP )
%
DV_PARAM= ( WING, 0, 8, 0, 0.0, 0.0, 1.0 );( WING, 0, 8, 1, 0.0, 0.0, 1.0 )
%
% New value of the shape deformation
DV_VALUE= 0.02, 0.02
%

On executing SU2_DEF, .su2 format of mesh is generated which is used as an input for the simulation. But on executing discrete_adjoint.py, I get the following error-

Error in "void CConfig::SetConfig_Parsing(std::istream&)":
-------------------------------------------------------------------------
DV_VALUE: DV_VALUE does not contain enough entries to match DV_KIND or DV_PARAM.

------------------------------ Error Exit -------------------------------

From the looks of the error and my config file, I do have equal number of arguments in the DV_VALUE as well as DV_KIND or DV_PARAM, which makes me wonder what might have caused this error.

I have attached my config file as well. Any help is appreciated. Thanks!

Hi, try placing the FFD_DEFINITION above those parameters.

[Daaman]

Hi, thanks for the reply. I tried placing FFD_DEFINITION above the parameters as suggested, but the same error pops up.

[Daaman]

Could this be a bug?

What version of the code are you using?

[Daaman]

I'm using version 7.1.1.

Ok... it looks like (yet another) bug of the python scripts, but SU2_CFD and SU2_CFD_AD work fine...
I'm one of the main developers and I never use those scripts, simplified interfaces are the root of all evil.

Thanks for looking that up. Yes, I was able to run the other solvers with FFD_SETTING though. But, it fails to run with multiple FFD_CONTROL_POINT. I'll open this as an issue on SU2's git.
