CS_4.0.2 and syrthes4.3.0 coupling issues

[ROLLAND]

Hi,

I recently followed the "Guide to couple Saturne & SYRTHES" for installing and coupling Code_Saturne and Syrthes in a forum. To check their installation, I just run the test case 3disks2D (Three-2D-disks.pdf).
It turns out that each domain (fluid and solid) without coupling is working. However, when coupling by both adding a term in "Conjugate heat exchange" in the saturne gui and syrthes gui, I have an error message.

Code: Select all

I changed in fluid/src/cs_user_coupling.c the value of allow_non_matching (according to the tutorial) for true instead of false but nothing has changed.
I check the file syr_cfd_coupling.c and the function ple_locator_extend_search actually do exist.
I don't know if I miss something during the installation process (PLE library ?) or a put a wrong parameter somewhere (the two different meshes not matching?).

Can someone help me?

Thanks!

Hello,

Which version of Code_Saturne did you install with Syrthes 4.3 ?

Did you use the PLE sublibrary from Code_Saturne, or a separate build ?

"ple_locator_extend_search" is a function which exists in Code_Saturne 4.0 / PLE 2.0 / Syrthes 4.3, but not in older versions, so I suspect an installation issue or a mix with older versions.

Yvan

Hi,

Thanks for your quick reply!
I have installed Code_Saturne version 4.0.2. I pre-installed Syrthes 4.3.0 before installing CS.
I located the PLE path from CS in the code_saturne_build folder, from which I installed CS. You can find the setup.ini and lauch.config for your consideration. I didn't install external library of PLE, assuming that CS already got the last version of it.
The PLE version is 2.0.1.
I hope I answered your question.

Hello,

In your syrthes.ini, you should not use libple from code_saturne_build (which may contain a different directory hierarchy), but from the main installation (destination) prefix, so in your case:

ple USE=yes /home/rolland/Code_Saturne_4.0.2

Best regards,

Hi,

Thank you! It's working!
The code compiles properly now. However in the calculation process (Starting calculation

MPI_ABORT was invoked on rank 0 in communicator MPI COMMUNICATOR 3 SPLIT FROM 0

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.
--------------------------------------------------------------------------
--------------------------------------------------------------------------
mpiexec has exited due to process rank 1 with PID 837 on
node rolland-Precision-WorkStation-T7400 exiting improperly. There are two reasons this could occur:

1. this process did not call "init" before exiting, but others in
the job did. This can cause a job to hang indefinitely while it waits
for all processes to call "init". By rule, if one process calls "init",
then ALL processes must call "init" prior to termination.

2. this process called "init", but exited without calling "finalize".
By rule, all processes that call "init" MUST call "finalize" prior to
exiting or it will be considered an "abnormal termination"

This may have caused other processes in the application to be
terminated by signals sent by mpiexec (as reported here).
--------------------------------------------------------------------------
 solver script exited with status 1.

Error running the coupled calculation.

Either Code_Saturne or SYRTHES may have failed.

Check Code_Saturne log (listing) and SYRTHES log (syrthes.log)
for details, as well as error* files.

 Error in calculation stage.

Even by lowering down the n_procs_max and n_procs_min to one processor in the coupling_parameters.py file, as well as in the CS GUI (Number of processes) and Syrthes (Scalar/Parallel calculation) GUI, the Starting calculation step still fails.
I decided to overcome this problem by writing mpi USE=yes PATH=/usr/bin instead of mpi USE=yes PATH=/usr in the setup.ini file to have a direct match in the path given in the lauch.config file. And the problem got worst:

Code: Select all

 Coupling execution between: 
   o Code_Saturne [1 domain(s)];
   o SYRTHES      [1 domain(s)];

That's weird as MPI library is installed in /usr/bin not in /usr unless Syrthes recognize the path to follow from /usr.
Or did I miss something in the configuration/parameters of the fluid/solid domains?

Sorry for this long answer,

Hello,

Now that the code seems installed correctly, could you move future usage questions to the "general usage" section of the forum (and adapt the info/logs to that section's recommendations) ?

Did you create the tutorial coupling directory structure using "code_saturne create -c fluid --syrthes solid" ? You do not seem to have the correct directory structure for a coupled case.

Regards,

Yvan
