Hello Yvan,

I appreciate your help! The mesh is small and I attached it here. I use the master version from GitHub.

It seems a simple case so I really want to know why is this error.

Best regards,

Hello Yvan, Thank you very much, I really appreciate your help. I tried this method but without success. Could you guide me where is wrong please? Now my model is rotating along x axis, the rotating speed is 10 rad/s. I tried in GUI, set omega_x=10.0 s^-1. I also tried to set it in the subroutine. B...

Hello Yvan, Thanks a lot for your comments! I really appreciate your help! Sorry for not running the same timesteps for each case. I also use the average time for each step, the same as your method. Actually not all the cases are on a single node. I have 28 cores per node. So for the 2cores and 28co...

Hello Yvan,

Here follow the timer_stats.csv files. They may help. Thank you!

Hello Yvan, Thanks a lot for your very useful comments. I have attached the performance.log files when using 2cores, 28cores and 56 cores. I really appreciate it if you could help check. Here are some details of my cluster: Processor type: Intel(R) Xeon(R) CPU E5-2660 v4 @ 2.00GHz Network type: op M...

Hi Yvan, Thank you! I still have no idea what to do with the previous error. But I tried other nodes with different features. Then all the errors disappeared. I think some nodes on my cluster are not compatible with Saturne, or need special settings maybe, for some reason. I tested the parallel perf...

Dear developers, Could you please help me with this question? I use the latest master version with GUI. My model is a closed rotating cavity, shown in the figure below. I want to put the entire domain in a rotating reference frame. So for the "Turbomachinery model", should I use "Froz...

Hello Yvan, Could you please help me with this error? I ran a test case in parallel on cluster, using the setting that you recommended, but still can't do it. I have 1 node with 27 CPUs. I set "n_procs: 27, n_threads: 1" in run.cfg, but the calculation can't start. The error is shown below...

Hi Yvan,

Sorry I miswrote the control_file. Just add a number "1" into control_file, and copy it to the result folder will work.

Many thanks,

Dear developers, Please could you help me with this question? I did the "heated square cavity flow" tutorial case recently, but I am confused about the way it applies the Boussinesq approximation. I suppose the Boussinesq approximation only changes density in the gravity term, from a const...
