Salome-CFD missing librairies issues

Post by emilie.powaga »

Hello,
I am a novice on Linux and Salome-CFD code.
I have problems with the saturne code due, I think, to missing package during installation.
- Ubuntu version installed on the machine : 16.04.5 LTS amd64
- Version code Salome-CFD: V8_5_0 - code saturne V5.3

During the installation of the Salome-CFD code, I had 3 warnings :
- directory /home/emilie/bin is a path variable but does not exist.
- directory /home/emilie/.local/bin is a path variable but does not exist.
- directory /snap/bin is a path variable but does not exist.

After installation, the application did not want to open. I understood that it was missing the "libgfortran3" library, which I installed. Since then, it opens without problem, and I was able to make the "cavity" tutorial almost entirely.

The software crashes when I want to run CFD simulations in the saturn code module of the application. Apparently this time, the libmpi.so.12 library is missing. I installed the mpich package, hoping to solve this pb, but this is not working this time.

Can you help me to solve this pb?

Thank you in advance,
Emilie

Hello,

The MPI library the Salome_CFD was built with was OpenMPI, not MPICH, so you should have more luck with this.

Also, salome_CFD 8.5 is obsolete, and code_saturne 5.3 is not maintained anymore, so I would rather recommend a separate code_saturne and salome install with more recent versions (we tried building recent versions for Ubuntu 18, but had some build issues on some dependencies, and di not have time to finish this yet).

Best regards,

Yvan

Thank you for your quick answer.
I will try to install openMPI package. If it's not working I will try to install separatly salome and code-saturne.

In my experience ... If you already have a working Salome environment for geometry meshing and maybe postprocessing there is very little, if any, benefit from the integration of Code Saturne with Salome compared to the integrated gui. I actually also prepare a separate installation of Paraview above the Paravis module as it is much more efficient. Quitting Salome when not needed also increase the memory available to other processes. So I would consider the loss bearable.

Hello,

I would add that after the 7.0 release (and possibly in 7.0 based on feedback of the master development branch), the salome_cfd extensions (CFDstudy) are installed separately, to avoid issues with users desperately trying to install the integration, while it is not essential for a working code_saturne installation.

Best regards,

Yvan
