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...

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...

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...

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

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...

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,

Hello, I have created a user defined field inside cs_user_parameters.c (I underline .c), through "cs_field_create". Nevertheless, I am not able to find a way to activate its post-processing... Anybody knows what is the function I have to use for that? Thank you very much in advance. Best r...
