Re: Error while launching cs under MacOS

Hello, In the src/base/cs_ale.c file, there is a "_cs_glob_ale_data" structure, and a "cs_glob_ale" pointer pointing to that, but no variable named "_cs_glob_ale". You can try renaming "_cs_glob_ale_data" as "_cs_glob_ale_data_s" for example in that ...

Re: Cannot launch GUI due to Qt error

Hello, I had not previously noticed that your Qt5 install seems to be local to your home directory, so not from the base Linux distro, but from some other packaging or install system (pip or Conda I assume ?). Which version of Qt was detected at install (this is why logs are mentioned in the forum u...

Re: Code_Saturne citation (trademark or registered trademark?)

Hello,

I would need to check the details, but the trademark is registered in France and several other countries.

Best regards,

Re: Convergence study in Code_Saturne

Hello Yang, The default is centered. Or more precisely, centered with slope test. When the slope test kicks in for a given face, it locally switches to pure upwind (for that face and operation), so the convergence order drops to 1. (There is an advanced setting allowing to use blending here, but it ...

Re: Mixture multiphase model

Hello Luciano,

I guess this would be possible using the drift model. I have not gotten an answer yet from colleagues when relaying rhe question, so I'll ask again.

Best regards,

Re: Convergence study in Code_Saturne

Hello, That is reassuring. Now that your postprocessing does not interfere with the convergence order measurement any more, I gues you should also get something close to 2nd order with SOLU, though I do not expect it to be more precise than the centered option (though it may be more robust on distor...

Re: Use of Azure Batch or Google Cloud HPC to run simulation on cloud cluster

Hello, There have been successful tests on AWS clusters using ARM Graviton processors, including large cases on more than 1000 cores (and we are working on improving the settings for this type of configuration), but I do not know of any runs on Azure or Google cloud infrastructures. Basically, there...

Re: Convergence study in Code_Saturne

Hello,

Other important question, how do you measure the error ? Which type of data do you extract ? Do you interpolate it in any way ?

Regards,
