Re: CGNS: error checking file type
Hello, This error means a CGNS library call (cg_is_cgns) checking that the file is indeed a CGNS file has failed. This could be a bug in the CGNS library (we have tested 4.1.2, 4.4.0, and some 4.3 versions I think, but I am not sure about 4.1.0), and install issue (if CGNS is not built with HDF5 sup...

Re: salome to code_saturne
Hello,
This should be in the code_saturne usage section, so I may move this topic to that section soon.
The preprocessor log you posted explains the problem: you have only meshed the cylinder's surface, not its volume. So you need to fix your mesh.

Yvan

Re: 2 questions related to Code_Saturne usage
Hello, 1) I think this is the zone of the volume. 2) If you need to compute some combination of z and z_gound, I would use ParaView's calculator. There is also a calculator in the development branch of code_saturne, but I would recommend using the combination that requires the smallest volume of I/O...

Re: Code_Saturne on hpc
Hello,
Could you follow the forum usage recommendations and provide the relevant logs ?
On the cluster, are you starting the code from the GUI or "code_saturne submit" ? Is the post-install (etc/code_saturne.cfg) step done ?

Yvan

Re: Strange Halting at Half Total Iterations
Hello, Yes, this is the default : except for test runs of 10 iterations or less, there is a checkpoint every 1/4 of the total number of iterations required. Again, do you know if there was an "upgrade"/maintenance of some librairies on your cluster ? Do you have access to other MPI librari...

Re: Strange Halting at Half Total Iterations
Hello, With version 8.1, you should not have the code_saturne "race condition" bug. So this might be a problem in the system. Did you reproduce it a second time ? On our machine, we had the issue with OpenMPI 4 and 4.1 (less frequent with 4.1), but this depends on lower level elements of t...

Re: Strange Halting at Half Total Iterations
Hello, I forgot to ask/you forgot to remind me which version of the code you are using. There was in issue in the restart code some time ago (more then 2 years if I remember) where we could also have a race condition leading to the behavior you observe. Otherwise, if the issue only happened once, tr...

Re: Strange Halting at Half Total Iterations
Hello, What type of machine/compute environment are you running on, how many MPI ranks do you use, and how long has the code been running ? This seems to be a hang when writing an intermediate checkpoint file, and may have similarities with some issues we encountered on a cluster following a system ...

Re: Scalars and RIJ ssg
Hello,
I have suggested to some colleagues more expert in.the turbulence modeling of the code to check this post... I'll ping them again.
Best regards,
