Re: Volumetric source term missing - Syrthes/CS coupling

Hello, Volumic coupling is used for volumes that are both fluid and solid (i.e. zones with some form of porosity or cluttered regions, containing both fluid and solid portions, at a level of detail smaller than the mesh resolution). Surface coupling is used for the classical cases where a surface se...

Re: Volumetric source term missing - Syrthes/CS coupling

Hello, If you are doing a volumic coupling, you need to define it in code_saturne using a user subroutine (see cs_user_coupling.c and associated examples), as the GUI only allows the definition of surface coupling (and using a 2D projection, a surface is considered a volume in the "original" space)....

Re: Unable to run a coupled simulation with Syrthes

Hello,

I don't know, it was a SIGSEGV, and on an old version.

What logs do you have ?

Regards,

Re: Sort the exported data in parallel mode

Hello,

Did you look at the probes and profiles documentation ? It seems it would be adapted to what you are doing.
Otherwise, export to EnSight format, and extract the data to CSV using ParaView.

Regards,

Re: Disable exporting a field in post-processing stage

Hello, Check for "Postprocessing output" in https://www.code-saturne.org/cms/sites/default/files/docs/6.0/doxygen/src/parameters.html , adjust for the field name, and replace CS_POST_MONITOR with "0". In other words: cs_field_set_key_int_bits(cs_field_by_name("user_field"), cs_field_key_id("post_vis...

Re: Periodicity and scalars LES

Hello, Thanks for the feedback on the extra element for the profiles. I had encountered this once before but it seems we have not made the code robust in this regards yet.... For the other issue you have, I would indeed be interested in the full test case, but if you have a smaller version of the me...

Re: Issues installing CGNS with install script (6.0)

Hello, The log does not provide any additional info that I know how to use. The issue might be due to "too old" CMake version on the cluster. I am not sure, but I have both encountered cases where a too old verson of CMake would lead to an error message and others where there was not error message b...

Re: Issues installing CGNS with install script (6.0)

Hello, Could you post the /share/apps/code_saturne/saturne_build/CGNS-3.4.0.build/CMakeFiles/CMakeOutput.log file mentioned in install_saturne.log ? Otherwise, perhaps you can try to install CGNS "manually", using "ccmake -i" in /share/apps/code_saturne/saturne_build/CGNS-3.4.0.build to try to check...

Re: Abnormal increase in linear solvers elapsed time for LES WALE

Hello,

Is the code otherwise behaving well, or could it be diverging (in whch case you would probably observe an increase in the Courant number in the run_solver.log) ?

Regards,
