Re: Axail fan modelling usin cs_fan.h

Hello Luciano,

I might be able to find an old report (in French) in which 1 or 2 pages describe the model and might provide a reference. I need to do a bit of archeology on my machine, but I'll let you know.

Best regards,

Yvan

Re: Stop to avoid exceeding time allocation on cluster system

Hello,

No, simply running "make install" should be enough.

Do you still have the message about a time limit ? It is handled in the same file (cs_resource.c), so returning immediately should avoid it...

Best regards,

Re: ALE simulation v5.0.3 vs v6.0.2 discrepancy

Hello, Yes, all v5.0.z and v6.0.z are normally stable versions. Versions 5.0.0 and 6.0.0 contain all bug fixes detected at validation, and later versions either ports to other machines or additional bug fixes. Actually, I am not sure we have an "internal coupling" test case in the validati...

Re: Stop to avoid exceeding time allocation on cluster system

Hello, Regarding the parsing of the wall time, I will need to add a test for cases where squeue -h -j $SLURM_JOBID -o %L returns a multi-line answer. Otherwise, it is possible that the margin is not computed correctly. You can try editing src/base/cs_resource.c, and add a "return;" stateme...

Re: k-omega SST discrepancy between v516 and v530

Hello Frank,, both versions 5.1 and 5.3 are "retired" versions, which were never fully validated (compared to v5.0, v6.0, and soon v7.0) and are not maintained anymore, so we only run these versions anymore, except as a last resort to trace a regression, when all other means fail, as this ...

Re: Stop to avoid exceeding time allocation on cluster system

Hello, In the post-install step, in code_saturne.cfg, just set (uncoment) batch=SLURM. You can also replace SLURM with an absolute path name ending in SLURM, if you wand to defined you own header model rather than that defined in extras/batch/batch.SLURM in the source tree. When that is done, if you...

Re: Stop to avoid exceeding time allocation on cluster system

Hello, I do not recommend running the whole "runcase" script under srun, and in any case, have never tried. If you install code_saturne correctly, including the post-install step with the "code_saturne.cfg" file (see installation documentation), you shoud just run "sbatch ru...

Re: Stop to avoid exceeding time allocation on cluster system

Hello, What batch system is used ? How long did the computation run ? How much time was allocated in the batch submission. What is the general information on your case as listed in the forum usage recommendations ? On a cluster, even if you run ulimit in a symbiotes script, it is often not relevant,...

Re: 1D-wall thermal module

Hello, No, the example you are using is the best we have. Actually, I do not encourage using that model, except in cases where you are sure the transverse heat conduction effects can be ignored, and a better approach is to use an extrusion of the boundary (or in more complex cases, a conforming join...

Re: ISCHTP when IDDES = 1

Hello,

Sorry for the late answer. I talked about this to the developer who implemented the DES models, and he said it was a very good question :-). It seems some things need to be tested first, but he should provide you a more detailed answer soon. I'll remind him.

Best regards,

Yvan
