Issues with Preporcessor

[Debashis Basu]

Hello,

We are having a problem with Saturne. One of my colleagues is trying to use this.  We are thinking whether this is a version issue with Saturne.

----------------------------------------------------------------------------------------------------------------------------------------------- His message----------------------------------------This is the exact problem.
 
When running the preprocessor either through the SaturneGUI or the command line command check_mesh -m "filename" I receive and error message. The following are the exact error messages for each file format I have tired.  All of which, according to the manufacturers, is a supported type by Saturne 1.3.3.  However each of these file types processes normally on my laptop running Code_Saturne 2.0. Is this is a version issue ?. Any advice, would be appreciated.

Kindly advice. He was trying to simulate flow over a cylinder.

Hello,

This is an installation issue: you need to configure/build Code_Saturne with MED file format support for it to be able to read MED files. If a MED library and headers are installed in standard directories (such as when using med and med-dev packages under Debian or Ubuntu), Code_Saturne will support them automatically.

I believe the install script handles MED support also, if it is configured correctly.

If you colleague already uses a SALOME install, there is no need to install MED again: he can point to the MED libraries already included with SALOME (for the Preprocessor's --with-med=<med_root> configure option).

For the other formats, things are stranger, as they do not need additional libraries. Were those files generated under Lnux or Windows ? If they were generated under windows, they should still be readable, but running "dos2unix" if available would be a precaution (especially with the older Code_Saturne 1.3). Otherwise, can you post the output of "head -100 cylinder.unv" for example ?

Another possibility is an install problem. What is the OS and compiler ? If all else fails, could your collegue try a clean reinstall ?

Best regards,

Thank You very much.

For gambit, you should export in neutral format (.neu file). Try solver -> generic.
