I want to optimize an airfoil,but I want to set the AOA and airfoil shape as design variables, so I set:
% Optimization design variables, separated by semicolons
DEFINITION_DV= ( 1, 1.0 | airfoil | 0, 0.05 ); ( 1, 1.0 | airfoil | 0, 0.10 ); ( 1, 1.0 | airfoil | 0, 0.15 ); ( 1, 1.0 | airfoil | 0, 0.20 ); ( 1, 1.0 | airfoil | 0, 0.25 ); ( 1, 1.0 | airfoil | 0, 0.30 ); ( 1, 1.0 | airfoil | 0, 0.35 ); ( 1, 1.0 | airfoil | 0, 0.40 ); ( 1, 1.0 | airfoil | 0, 0.45 ); ( 1, 1.0 | airfoil | 0, 0.50 ); ( 1, 1.0 | airfoil | 0, 0.55 ); ( 1, 1.0 | airfoil | 0, 0.60 ); ( 1, 1.0 | airfoil | 0, 0.65 ); ( 1, 1.0 | airfoil | 0, 0.70 ); ( 1, 1.0 | airfoil | 0, 0.75 ); ( 1, 1.0 | airfoil | 0, 0.80 ); ( 1, 1.0 | airfoil | 0, 0.85 ); ( 1, 1.0 | airfoil | 0, 0.90 ); ( 1, 1.0 | airfoil | 0, 0.95 ); ( 1, 1.0 | airfoil | 1, 0.05 ); ( 1, 1.0 | airfoil | 1, 0.10 ); ( 1, 1.0 | airfoil | 1, 0.15 ); ( 1, 1.0 | airfoil | 1, 0.20 ); ( 1, 1.0 | airfoil | 1, 0.25 ); ( 1, 1.0 | airfoil | 1, 0.30 ); ( 1, 1.0 | airfoil | 1, 0.35 ); ( 1, 1.0 | airfoil | 1, 0.40 ); ( 1, 1.0 | airfoil | 1, 0.45 ); ( 1, 1.0 | airfoil | 1, 0.50 ); ( 1, 1.0 | airfoil | 1, 0.55 ); ( 1, 1.0 | airfoil | 1, 0.60 ); ( 1, 1.0 | airfoil | 1, 0.65 ); ( 1, 1.0 | airfoil | 1, 0.70 ); ( 1, 1.0 | airfoil | 1, 0.75 ); ( 1, 1.0 | airfoil | 1, 0.80 ); ( 1, 1.0 | airfoil | 1, 0.85 ); ( 1, 1.0 | airfoil | 1, 0.90 ); ( 1, 1.0 | airfoil | 1, 0.95 ); ( 102, 1.0 | airfoil )

other is the same as the example inv_NACA0012.cfg
and I face a error:
Command = C:\SU2\SU2_CFD config_CFD.cfg
SU2 process returned error '1'
ERROR: Cannot find value AOA in given map.
Please check the name of the variable in the config file.


I hope your rely.thank you

Are you sure you didn't remove the comment from the DV list?

Changing:
% - AOA ( 102, Scale | Markers List )

Into
AOA ( 102, Scale | Markers List )

Thank your rely,I want to clear the question again.

I'm not really sure to be honest. I've worked to make the config parsing better for the upcoming release (whatever the problem is, your error will be better soon).

My guess would be that your angle of attack variable is set to AoA. Could you try changing that to AOA and see if it fixes the issue?

I'm not really sure to be honest. I've worked to make the config parsing better for the upcoming release (whatever the problem is, your error will be better soon).

My guess would be that your angle of attack variable is set to AoA. Could you try changing that to AOA and see if it fixes the issue?
Hi ,Brendan Tracey,thank your reply fastly,I am sorry that I do not understand your answer fully,if I delete the last order( 102, 1.0 | airfoil ),it has not error,but the AOA is fixed.
But I want to optimize the airfoil when the CL is fixed,solving the AOA and airfoil shape that is similar to reverse design,because I see the AOA can set the design variable,so the AOA can be setted as incidence angle in 3D wing.

Hi,

Just to follow up on this thread.. you might want to give the new fixed AoA mode in SU2 V3.2 a try for your problem. This doesn't directly address the shape design problem, but you may find it interesting. You can activate it with the following new options:

% Activate fixed lift mode (specify a CL instead of AoA, NO/YES)
FIXED_CL_MODE= NO
%
% Target coefficient of lift for fixed lift mode (0.0 by default)
TARGET_CL= 0.0
%
% Damping factor for fixed CL mode (0.1 by default)
DAMP_FIXED_CL= 0.1

All the best,
Tom

Sorry,I recompute the file lately,I hope that the airfoil shape and AOA is changing at the every time calculation,but I change the file form your advise,
it seem change the AOA only,the mesh is not change,and the situation is unstable.
My file is
inv_NASA0712.zip
If you need my mesh, call me and sent the mesh by email.
Thank you

Hi,

Just to clear this up (my original post may have been a little misleading). The new fixed lift mode is not set up for use with optimization, rather, I just wanted to alert you of it's existence so that you can experiment with it for your analysis problem. Apologies for any confusion,

T

So the AOA can be not as the DV for the SU2 in the shape optimization??
