Hello,
i've got a problem when import a mesh file .med in saturne2.2.
When i import fluid mesh and i check it i receve this errors:


/usr/local/libexec/code_saturne/cs_preprocess --post-error ensight --case
preprocess /home/andrea/studio54/MESH/meshfluidamed3giusta.med

/usr/local/libexec/code_saturne/cs_solver: error while loading shared libraries: libsaturne.so.0: cannot open shared object file: No such file or directory

anybody could help me? thank you all

Hello,

It seems the shared library cache is not updated (this has been reported in the past, but we have not reproduced in on our Linux distributions).

There are 2 options:

If you have administrator (or sudo) priviledges, run: /sbin/ldconfig

Otherwise, add:

export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH

to your .profile file.

Best regards,

Yvan

Thank you Yvan, i've just solved running ubuntu updates (i was on a fresh installation of ubuntu 12.04 ) checking the option "not supported updates (precise-backports)".
After the reboot saturne could read the mesh .med . I still don't know why but we could set the post as solved !

Hello,

OK, fine. Actually, when you run an Ubuntu update, it probably calls /sbin/ldconfig, so the problem may have been solved in an indirect manner.

Regards,

Yvan
