Hi everyone,

I have a problem about shape optimization. I use Windows 7 and I installed NumPY SciPy and Python 2.7.

When I want to use any Python file in cmd I get a error like
Traceback( most recent call last):

File "C:\SU2\shape_optimization.py", line 26, in <module>
import SU2
ImportError: No module named SU2

How can I solve this problem?

Kind Regards

I seem to be getting the same exact error. I have SU2_RUN set to the path, I ran the case successfully just using SU2_CFD. I'm not 100% sure numpy and sipy are installed, however this seems to be a problem with SU2. Any ideas?

Ok, I've gotten further along. Posting solution for those to come.

The primary problem was that the SU2 python folder was missing with the __init__.py and such from the windows pre built version. To solve download the source code and copy the ..\SU2\SU2_PY\SU2 folder to the fully installed location.

My next step was to install numpy and scipy.

After aplying it I get

You are right. I reinstalled python to 2.7.x and it worked.

Now I am getting the following error:

PS C:\cygwin64\home\lmir\su2\optimization_euler\ rotating_naca0012> python.exe c:\SU2\shape_optimization.py -f .\rot
ating_NACA0012.cfg

Sorry! You were supposed to get help about:
orterun:exe-not-accessible
But I couldn't open the help file:
C:\DBD\pvs-x64\install\share\openmpi\help-orterun.txt: No such file or directory. Sorry!
------

Any hint how to tackle this?

I'm sorry did you find solution to the last error. I have the same thing.


Code:
PS C:\SU2> python parallel_computation.py -f test/inv_NACA0012.cfg
2 total processes failed to start
SU2 process was terminated by signal '125'

I assume it is a problem with openmpi?

Yes. The problem is with OpenMPI you don't have. Try to execute with mpiexec, instead of with mpirun. Before doing that check that your MS MPI is installed.
