Dear Code_Saturne users,

Using Code_Saturne for atmospheric flows, I have some difficulties in order to maintain input meteo profiles (initially generated through idealized large scale meteorological data) on a flat terrain with stable conditions (it's quite fine for both neutral and unstable conditions). Any feedback/suggestion on this?

I'd like to make some tests by changing IWALFS (in order to test CS_WALL_F_S_MONIN_OBUKHOV while default is CS_WALL_F_S_MONIN_LOUIS), could someone tell me where this can be done since this parameter does not seem to be accessible in the GUI?

Kind regards

Julien C.

Hello,

It does not appear in the documentation, but if you search for MONIN_OBUKHOV in the src/user_examples/cs_user_parameters-base.c file, you will find an example.

Best regards,

Yvan

Thanks a lot!

Hi Julien,
Stable meteo-conditions is harder to simulate. But you can try to turn on Boussinesq approximation and maybe decrease a bit solver precision on "pressure"
