Hi,

Is there an example for how to do Code_Saturne/Code_Saturne coupling? And, is the turbomachnery module (now available through GUI) a Code-Saturne/Code_Saturne coupling under the hood? How is that done? Thank you very much.

Hello,

There might be old examples if you search this Forum for old enough messages...

The code/code coupling is used in 2 forms:

- the old rotor/stator coupling model (for which we have a regular test case, so I could provide that setup as an example, though I need to check if I am allowed to provide the mesh)

- RANS/LES coupling, rarely used, for which documentation might be sparse

The newer rotor/stator model (the one available through the GUI) does not use code coupling under the hood, but rather mesh coupling (so it is better conservativity-wise, does not require sub-iterations, but is more picky about mesh quality at the rotor/stator interface.

Regards,
