Hello,

I recently installed Code Saturne v3.3.2, using CFDStudy with Salome v7.4.0 on Ubuntu 14.04.

I was following the CFDStudy tutorial, and managed to get through all the pre-processing, however, when I click run, I get an error message:

I do not understand what is wrong...why can it not parse the file? Is the installation OK? Please help, new to code saturne...

Thanks in advance,

Peter

Hello,

I am not suite sure, but I seem to recall someone having a similar issue recently.

I suspect the issue is due to the combination of Code_Saturne's Python and Salome's python and/or their PyQt versions, but am not sure.

If you intend to use Code_Sature only through Salome, you could add PYTHON=<path_to_salome_python_exec> for Code_Saturne's "configure" command. You may also do the same for PYUIC4 and PYRCC4. The downside is that to use Code_Saturne directly, you will need to source the Salome environment (otherwise, Python will not start, as it will not find its libraries).

Otherwise, you could try running the tutorial from th Code_Saturne GUI directly ("code_saturne gui" instead of "code_saturne salome") ?

Yvan

Hi Yvan,

Thank you for the answer. I ran using saturne gui, and got a more helpful error: code saturne had been built without xml support. I had set the option to auto in the setup script, and got no error or message warning, so I though it had worked.

I've re-installed setting the option to install libxml2, and now it works...in serial. For some reason parallel compute process does not work. (I'll make a new post to keep it organised, including the log file from saturne).

Regards,

Peter

edit:

The solver ran using saturne gui, it does not run from salome, posting the following error (which I guess is related to python as python gets mentioned a lot):
