jobs stuck when writing checkpoint - CS v7
Hello, I am using version 7.2.0 and observing a problem never faced before. The simulation gets stuck once CS has to write either a checkpoint or a postprocessing periodic output. There is no error appearing, the job continues running, but practically it is stuck in the writing process forever... I ...

Re: Free memory constantly decreasing
Hello, Thank you for checking all this. The beta function is already available in the CS sources v7. You can find it at le line 195 of the cs_turbulence_kw.c (DDES). The only two additional allocated arrays that are created following the activation of this model are correctly freed at the end of the...

Re: Free memory constantly decreasing
Hello Yvan, Thank you for your help. I have found out that I had a beta function (for turbulence modeling) of CS v7 activated that seems to be the source of the memory leak. Switching to a "standard" turbulence model, memory does not seem to decrease anymore. Anyway, I have done what you s...

Free memory constantly decreasing
Hello, I am using v7 and facing some memory issues: the free memory of the nodes I run the job on is constantly decreasing, and the job at the end crashes. I have tried to run the job removing all user routines but the problem remains. Running the code with Valgrind indicates 0 bytes definitely or i...

modify cs_turbulence_kw.c
Hello,
Maybe it is a stupid question, but if I wanted to modify a routine such as the cs_turbulence_kw.c, I guess I am obliged to re-compile the code? I.e., I cannot just include it inside the SRC folder...?
Thank you very much for your help.
Kind regards,
Daniele

Re: restart problems with v7
Hello, To answer your previous post, we doubled checked and the jobs run correctly on all the processors: i.e., the report of 20 seems to be wrong, the specific job ran on two nodes of 40 processeurs each. I also checked my old jobs, and found out this reporting inconsistency also for versions 5 and...

Re: restart problems with v7
Sorry Yvan I missed your last post on this topic, that's why I have not replied before.
I will try to collect the information about our MPI environment and also try to build a small test case (the actual one is too big to be shared).
Thank you (and happy new year!),
Best regards,
Daniele
