Is there a reason why the attached xml file gives the error "Expressions are missing !" when you try to save it? In fact the file has nothing changed from the default except for creating an inlet with a prescribed "norm (user law)" and specified coordinates for the direction. Am ...

If I understand correctly, with a k-epsilon approach (iturb=20), the default wall-model is a two-scales log layer (iwallf=3). However, the documentation does not appear to correspond exactly to what is in the code. In particular, it seems that Eq. I.5.2 is not correct (which should instead correspon...

Are there any plans to add a few words and improve the theory guide relating to the "iphydr" option ? It is not entirely clear what has been implemented. The theory guide for both v5.0 and 6.0 in the pdf <https://www.code-saturne.org/cms/sites/default/files/docs/6.0/theory.pdf#iphydr> refe...

Ah, interesting, thanks ! I can confirm that it works. To say more precisely for those who may be interested, I was able to use C++ code without recompiling Code_Saturne -- first by using a ".cxx" suffix in the user routines in place of a ".c" suffix (for my test, cs_user_extra_o...

Has the status of C++ (or other languages) changed in recent years? I see that it's possible to include a C++ file with suffix .cxx, for example, which the Python bits will recognize and on my setup get compiled by g++, but gcc will still be used as the linker and then crash. Of course the missing p...

Just as a suggestion, perhaps this could be used to update the tutorial page (which still has documentation for running the test with version 2.0) ?

Is there any function within Code_Saturne which computes an FFT? Would it be possible to call it from a user subroutine? Obviously it would be possible to write a custom FFT function into a user subroutine, likely overly long or inefficient in the process, but if it (or a library that contained an F...

Just as a comment... Would it be possible in future versions to have access to x/y/z when setting the mesh velocity by the GUI with the mathematical expression editor, as it is already for setting the fluid velocity at an inlet? This could simplify the setup of a few interesting problems.
