Divergence optimization NACA0012 inviscid test-cases

[arrow206]

I am using SU2 version 3.2.8 on a Linux workstation. I am trying to optimize an NACA0012 for Euler flow Test_cases/Optimization_euler/steady_naca0012). The code diverged after 115 call to functions. I am including the output. If I am trying to read the error, it seems there is an issue with slsqp that is provided by Python. If this is the cases, what Scipy version of Python would you recommend?

python shape_optimization.py -f inv_NACA0012_adv.cfg -r 0

SU2 process returned error '2'

mpirun noticed that the job aborted, but has no info as to the process

that caused that situation.

No problem. It can be posted on the Forum. Sorry if I put in in the bad place.
