Hi,

I recently did the quickstart example here:

https://su2code.github.io/docs/Quick-Start/

However, I modified the mach and the AOA. The mach is fixed at 0.3. In one simulation the AOA is 2.8 and in the other it's 3.0. Here are the CL/CD outputs for each simulation:

AOA: 2.8 CL/CD: 3.7
AOA: 3.0 CL/CD: 841.20

This seems like a pretty big change for such a small AOA change. Does anyone know if this is correct?

Thanks,

-D

p.s. I don't think it's an optimization problem in the sense that the KKT condition is met after 215 and 263 iterations, respectively.
