Hello,

This seems correct. I just checked on my Ubuntu 12.04 install, and I do not have any issue.

Also, as the value in of SYRTHES4_MPIPATH in your syrthes.profile is correct, you should not have any error relative to MPI (the syrthes.py script only checks the path is defined, not that MPI is ...

Hello,

What is the value of SYRTHES4_MPIPATH string in your syrthes.profile file ?

There might be an issue in the MPI configuration for SYRTHES.

Best regards,

Hello,

Do you have a mpi.h in /usr/include ? What MPI version/packages do you have after all ?

If you do not need CGNS file format support, tell the installer not to use it. Otherwise, you may either use a packaged version of CGNS (but you will only have version 2.5), or install CGNS manually ...

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.

Hello,

Judging by the warning message for the optical length of the semi-transparent medium, your radiative source term seems too high, or your absorption coefficient too small. Did you try increasing it ?

Hello,

Your value of base wall flux density seems very small (wallflx = 1.8 * 10**-10), so I would expect the increase in scalars to be very very slow.

Can you test with a higher value (not so high that you crash the calculation, but using a value so that the flux density/(specific heat equivalent ...

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 ...

Hello,

Yes, the SYRTHES team is in the same departement, less than 20 meters away, but they do not seem too interested in the Autotools, even with assistance.

Actually, only a few of us in the Code_Saturne team are really familiar with the the Autotools, and building an install which allows user ...

Hello,

You might have some other error in the setup for version 2.1.

Did you try addr2line for the other addresses in the backtrace (from top to
bottom) ?

Hello Martin,

Yes, things would probably simpler if SYRTHES also used the Autotools, but the development team is small (2 people, who work only a fraction of their time on the code, + occasional subcontracting for the GUI and tools).

Regarding /usr as a path for MPI in setup.ini, this should work ...
