Installation of Code_Saturne 3.0.3 and Salome 7.3.0

[Yvan Fournier]

Hello,

Can you open the XML file normally with Code_Saturne's GUI (under CFDSTUDY, right-click on the tjunction.xml file, in Code_Saturne standalone mode, run "./SaturneGUI tjunction.xml" in the DATA directory) ?

Regards,

Yvan

Hello Yvan,

Thanks again for your prompt answer.

Yes, I can launch the computation with Code_Saturne in standalone mode.

Do you then have any advice to help me fix this issue?

Hello,

This is quite strange. I suspect a conflict between multiple Python variants or Code_Saturne package variants. Do you have multiple installs of Code_Saturne ? of SALOME ?

Coul you temporarily edit your /usr/local/apps/Code_Saturne.3.0.3/lib/python2.7/site-packages/code_saturne/cs_xml_reader.py file, so as to replace (lines 124-127)

Code: Select all

         try:
             self.doc = minidom.parse(fileName)
         except Exception:
             raise XMLError('Error parsing XML file: ' + fileName)

with:

Code: Select all

         self.doc = minidom.parse(fileName)

This will let Python provide a more detailed backtrace, which may provide more info.

Best regards,

Yvan

Dear Yvan,

I modified the Python script as proposed and here is attached the output file. I don’t know if you’ll get enough information to understand the problem.

In order to answer your question, I don’t have another installation of Code_Saturne.

I also suspect a conflict as there are multiple Python libraries in my installation :
• /usr/local/apps/SALOME/Python-2.7.3/lib/python2.7
• /usr/local/apps/Code_Saturne.3.0.3/lib/python2.7/site-packages/code_saturne
• /usr/lib/python2.7

However, I don’t know how to properly suppress this conflict.

Thank you.

Regards,

Clément

Hello,

Your output is surprising. When you edited th file, did you reindent the line with minidom.parse ?

From:

Code: Select all

        if not os.path.isfile(fileName):
            raise XMLError('XML file: ' + fileName + ' not found')

        try:
            self.doc = minidom.parse(fileName)
        except Exception:
            raise XMLError('Error parsing XML file: ' + fileName)

        self.root = self.doc.documen

You should go to:

Code: Select all

        if not os.path.isfile(fileName):
            raise XMLError('XML file: ' + fileName + ' not found')

        self.doc = minidom.parse(fileName)

        self.root = self.doc.documen

And not:

Code: Select all

        if not os.path.isfile(fileName):
            raise XMLError('XML file: ' + fileName + ' not found')

            self.doc = minidom.parse(fileName)

        self.root = self.doc.documen

Because indentation decides where we are relative to a loop in Python.

I ask this because your output is what would be expected if the "self.doc = minidom.parse(fileName)" statement is not executed.

Best regards,

Yvan

Hello,

You are absolutely right. Actually, I'm not familiar with Python. Sorry about that...

Here is the output with the right indentations :

Code: Select all

Thank you for your help.

Hello,

Sorry for not answering earlier. This is very strange, as it looks like an install issue, but as both SALOME 7.3 and Ubuntu 13.10 use Python 2.7 (unless you chose to install Python 3 as a default under Ubuntu, but I am not sure it is even possible).

I can't even run SALOME 7.3 anymore on my Ubuntu 14.04 beta, so I can't test, unless I run on a virtual machine (I'll have to reinstall SALOME first, and if it's not enough post to the salome-platform.org forums, but that is another issue).

Next week will be very busy with our user meeting, so I probably won't have time to look into this, but I'll try to get back to testing this in 10 days.

Best regards,

Yvan
