When I use shape_optimization.py to optimize an airfoil in the tutorials, I cannot put thickness or area as constrants due to this error:


Traceback (most recent call last):
File "/.../shape_optimization.py", line 183, in <module>
main()
File "/.../shape_optimization.py", line 92, in main
shape_optimization( options.filename ,
File "/.../shape_optimization.py", line 110, in shape_optimization
config = SU2.io.Config(filename)
File "/.../SU2/io/config.py", line 123, in __init__
tavg_keyGroup = "TAVG_" + historyOutFields[key_inner]["GROUP"]
KeyError: 'AIRFOIL_THICKNESS'


However, adding the constraint of lift or drag can work well.
But the area and thickness can be found in config_template.
How can I solve this problem? Thank you very much.
