Issue with the VLM code when it is used to size the TBM aircraft. The second angle of attack, INPUT_AOA = 10, causes troubles for the code to converge. When it is set up at 5, the polar looks better. However, there is no problem when the sizing is done with OpenVSP.
So, to use the VLM method, we have to change the value of INPUT_AOA. This could be done by adding an option in OpenMDAO.
