SU2 stopping after first design cycle

kaush · December 7, 2018, 02:25

Hi

I am running the shape_optimization.py for a wing body configuration. I have given a fixed cl. My optimization process stops after the first design cycle. I also tried changing the tolerance parameters, number of iterations but it does not seem to go through. I am attaching a copy of the cfg file. any insights would be valuable.

Regards

Relaxing your constraints may help you.

You use SU2v5.0.0 version right? If you use this version and use a fixed cl. mode, the CFD direct calculation process won't exit successfully. I met a situation that SU2 process returned error '6', but when i use a fixed aoa mode, the problem is avoided. I assume that this is a bug in SU2v5.0.0. I test SU2v6.2.0, the bug has already been fixed. You can try a newest version.
