Hello,

I have a similar problem when trying to write output files in the ensight format. The compilation works succesfully but an error appears during the execution (erreur à l'execution du noyau). This error also occurs with the stand alone Saturne under CAELinux 2007. It works well when writing the output files in the med format.

The erreur file gives the following output:

Signal SIGSEGV (accès à une zone mémoire interdite) intercepté !

Pile d'appels:
1:0xffffe420 ? (?)
2:0xb7f857a6 <fvm_writer_init+0x3d6>
3:0x806b765 <cs_post_ajoute_writer+0x136> (cs13.exe)
4:0x806c80f <cs_post_init_pcp+0x147> (cs13.exe)
5:0x805c269 <main+0xlad> (cs13.exe)
6:0xb79e975c <__libc_start_main+0xdc> (libc.so.6)
7:0x805c021 ? (?)
Fin de la pile

Did somebody already have a similar problem? Is there a known way to fix this problem?

Thanks

Stephan

Hello,

on my laptop (Intel Core2Duo), I can successfully write results in Ensight format and it works well when loaded in Visit or Paraview...

It may be a platform compatibility problem... or a bug, but it's hard to tell.

Maybe you can try to recompile the code for your own platform, it should allready be configured correctly. Try also to recompile the ATLAS lib in the src subfolder. Depending on your hardware architecture, the ATLAS lib may not be running well (it was compiled for Core2Duo with SSE2)

Good luck

Stephan,
I initially had problems reading the ensight files in to Paraview, but resolved the error by selecting the "little endian" option when reading the files output by Saturne.

hello robin,

Thanks for your help. I still have some problems for the generation of ensight output files with code_saturne. I'm just trying to reinstall it from the scratch.

regards

Stephan
