Hello,

when I use shape_optimization.py on the ONERAM6 inviscid test case i get the following error:

Traceback (most recent call last):

I'm running SU2-4.0.2 on a Ubuntu-14.04 VM with a parallel configuration(with mpich2, if it can be of any help). I get the error either if I'm using one or multiple cores. I have no idea of what is causing the problem: did anyone experience the same error? I have read of similar problems in older versions of the software, but the proposed solutions didn't fit my configuration.

Thank you for your attention.

Hi Ullixes91,

could you try the new Version 4.1? If this problem still persists, please open a bug report on github.

Thanks!

I shall try to install it as soon as possible, and report the result. Thank you.

I believe that it is also possible for this error to occur if an incorrect number of design variable parameters have been specified - there are some failsafes in the code to catch that sort of thing, but it will not hurt to check that your design variable definitions have the right number of parameters if other solutions do not work for you.
