I use Ubuntu system. My conditions are:

1. install python, numpy, scipy, metis, mpich2,such as
sudo apt-get install mpich2

2. I set the SU2_RUN= /home/username/SU2v2.0/trunk/SU2Py

3. I type "python ./build_SU2.py -o redhat", so the executable files (SU2_CFD, SU2_GPC etc.) are generated in SU2Py directory.

4. Move the inv_ONERAM6.cfg and mesh_ONERAM6_inv.su2 into SU2Py directory

5. Type python shape_optimization.py -f inv_ONERAM6.cfg -p 4

At the beginning, the preparing process goes well, I can see the generation of Domain 1, Domain 2,Domain 3,Domain 4, but then I obtain some errors:

Could you please try again with the latest version of the code in the GitHub repository ( https://github.com/su2code/SU2 ) ?

Thanks!

Francisco
