Hi everybody,

I'd like to couple saturne-2.0 with syrthes4.0.1 instead of using the older version of syrthes3.4.2. Is it even possible to do and if YES what do I have to consider when starting a coupled calculation in this case? I still have experiences in coupling saturne2.0 with syrthes3.4.2. I suppose there are some rearrangements required in runcase or runcase_syrthes ??? Thanks for your help

Best regards

Hello,

Short answer: no, it's not possible.

Long answer: code initially intended for Syrthes 4.0 is in place in Code_Saturne 2.0, but as Syrthes 4.0 was released more than a year later, other changes have appeared, and this code would require switching from the external FVM to the external PLE + internal FVM library API's.
In addition, the case directory structure has changed, and the scripts might need quite a bit of work to attain something between current 2.0 and 2.1 scripts (this is probabl the most delicate part).

All in all, this would probably require at a few days for members of the developpement team who have already familiar with this part of the code (no more than 3 of us), and we are very busy with Code_Saturne 3.0, which is in a debugging/validation stage, with release planned next January.

As 2.0 is a "stable" version, backporting Syrthes 4.0 to Code_Saturne 2.0 is definitely not a priority, compared to improving the coupling in 3.0.

If you really need to do it, I can provide you more detailed recommendations, but I recommend upgrading to Code_Saturne 2.2 or 2.3 (or better, 3.0 if you are using the SVN mirror).

Best regards,

Yvan
