Hi every one.
I was trying to run one of the test-cases of shape optimization but I don't understand why when I used "shape_optimization.py module" the following errors appeared.


G:\naca0012>shape_optimization.py -f rot_NACA0012.cfg

How can I fix this problem?
please help me.
THANKs.

It looks like you are running this in windows, and SU2 is installed under Program Files. The command line call to the SU2 solver is failing because there is a space in the file path (Program Files). Try installing SU2 in a filepath with no spaces.

Hi Trent.
Thank you. After installing SU2 in another location, It did worked, but I faced another errors.
First of all two warnings appeared at the beginning of the program, and after that the magnitude of res(Rho) started to increase (Is this increase of res(Rho) rational?). and after 327 iterations another errors appeared and the program stopped.

Please help me.
Thank you.

You can ignore the warnings, they are referring to extra config options that the C++ side doesn't know about. Your log shows that the solution converged (it is reporting an exponent of 10 - i.e 10^-5.3 - so you want to see the residuals go to larger negative numbers)

The python error is a bit strange, it looks windows is having trouble renaming a file. Could you try deleting the DESIGNS folder, and any .plt files in your working directory for this problem, and try again? If you still get an error, please post the full log, and your version of windows and python.

Congrats! I did not get that far

when starting shape_optimization.py -f rot_NACA0012.cfg

on original SU2 download on Windows I had to :
1. add ..\SU2\SU2_PY\SU2 directory from the sources to SU2 installation directory as described here. Otherwise I get "No module named SU2" error.

2. add additional line to __init__.py in C:\SU2\SU2\run\__init__.py

--> from . import interface
from interface import \ build command , ...

Otherwise
No module named 'interface' error is triggered.

When fixed I get similar errors for other submodules, e.g. io (no module named 'tools')

Maybe I should use Python 2.x instead of 3.x ?

[Lukasz]

I reinstalled python to 2.7.x and it worked.

Now I am getting the following error:

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?
