Hello,

Could you provide an example of using new Launder-Sharma k-epsilon model in version CS 6.0? It would be great if you can provide wind tunnel with rough wall.

Best regards,

Yvan, thank you for your help! You are right that was a problem of ATHOS. I were running these case on EOLE and it works really well.
Thanks again.

Bon weekend,

Hello, Yvan, thank you for spending time for my case. I have checked this case with a smaller number of processors as you recomend. And anyway I have this error. If there is no memory leaks in there, I have only one guess that this case does not converge at some moment. Thank you again and bon weeke...

Hello!

Is that possible to simulate properly a flow over a very rough wall by k-omega SST model? I was trying a different tests and it does not gives me a proper velocity profile.

Best regards, Konstantin

Thank you for your reply, Yvan. I was trying the same test but with k-epsilon model and results gives me the same error "exceeded memory limit". So looks like problem not in the turbulence model. I attached zip archive with my setup files I was running on claster ATHOS usng 3 nodes. Best r...

Hello! I was running CS v5.3 and v5.2 with RSM LRR turbulence model, to calculate turbulent flow around cylinder. But this calculations are stopping after ~145000 timestep with error: slurmstepd-atcn451: error: Job 17541583 exceeded memory limit (61472984 > 61440000), being killed slurmstepd-atcn451...

Yes! You are right. Thanks for help Yvan!

Hello. I have a similar task. I was reading from GUI-defined csv-profile with velocity and turbulence statistics and use as boundary conditions. I was using C-version of files. You can find it here https://github.com/kikuznetsov/Code_Saturne-SRC . The source code is adapted for k-epsilon and Rij-eps...

Hello ! I have a problem with saving profiles using cs_user_postprocess.c in case Rij-SSG turbulence model (for k-epsilon works well). For the moment I am using this approach to create a set of points in the profile: cs_probe_set_t *pset = cs_probe_set_create_from_segment("Prof1", // name ...

Thanks a lot for your reply, Yvan.

At the end valgrind and your advice help me to find the memory leaks in my code.

Best regards,
