Hi

Well I had installed code saturne 2.0 because I wanted a stable version, but I had problems with the med files I created in salome 6.4 because I exported 3.0 med files and code saturne only could read 2.3.6 med files, I think.

So I read that code saturne 2.1.5 had support for 3.0 med files, so I uninstalled saturne 2.0 and I installed 2.1.5 version. The problem is that I get the same error when I import a 3.0 med file, saturne can't read it, What can I do? Could I modify a configuration file or should I reinstall?.

This is the error message when I click "check mesh" on the gui of code saturne:

Below I will put my configuration after running ./configure, Is it right? Should I modify something? Can I modify this parameters with a configuration file or should I reinstall? Is it a good idea to use the installer of the version 2.1.4?. I am a little bit new with linux and it was the first time I installed something with ./configure, make, makefile.

I forgot to mention that I tried to run an example but when I arrived at the final step, I clicked on the run calculation button but nothing happened, I don't know what file should I upload to show what was the cause of the problem, I searched on var for a log file with some name related with code saturne but I did not find anything, What information should I provide to you to understand the problem?.

Hello,

Version 2.0 can also support MED 3.0, but you have to build it with a MED 3.0.x library, not with a MED 2.3 library. Starting with 2.0.2, the automatic installer should install MED 3.0 instead of MED 2.3, but if this fails and you already have a MED 2.3.6 installed in system paths (such as with a Debian or Ubuntu package), the wrong version might be used.

Version 2.1.5 should also use MED 3, so I suspect that if your installation uses MED 2.3, you already had an install of MED 2.3, which was detected instead of 3.0 (which is either a bug or an error in tour installer setup file, so you should check your setup file for the MED path or options)

The problem with the "run" button is a separate issue, and should have been fixed after 2.1.5 (bugfix 2.1.6 will be released very soon).

Best regards,

Yvan

Hi Yvan

Well I tried some things but It did not work, for sure due to my lack of knowledge not for a bug.

Then I used the installer of the version 2.1.4 and now it reads mesh files in med 3.0 format.

Thanks for your answer.

Regards.
