Hello all,
I am currently getting the error message: 'Data' object has no attribute 'maximum_lift_coefficient'
Before this error message the following output is given:

EDFWing: EZSNEVDLZU

I went into the file:
File ~\AppData\Local\Continuum\anaconda3\envs\suave\lib\site-packages\suave-2.5.2-py3.9.egg\SUAVE\Methods\Missions\Segments\Common\Aerodynamics.py:186 in update_aerodynamics
CLmax = aerodynamics_model.settings.maximum_lift_coefficient
to analyse what the problem could be, but I wasn't sure where the maximum lift coefficient is calculated. For the Stall message I played around with the rotor parameters and included parameters from a working to get rid of this error message, but without success.
Did anyone experience this error message before and knows what the issue could be?
Thanks and best regards,
Tim
