Dear Support team,
I've seen the following recommendation in Code_Saturne general documentation (in Atmospheric flows module part):
In some case, the turbulent eddy viscosity can drop to unrealistically low values (especially with $k-\varepsilon$ model in stable atmospheric condition). In those cases, it is suggested to put an artificial molecular viscosity around $0.1 m^{2}.s^{-1}$.
Could someone please tell me where/how I can apply this recommendation in user subroutines?
Thank you in advance
I wish you a very pleasant week-end
JCo

Hello,
I'll need to check with atmospheric model specialists, but i would assume you can simply change the viscosity in the GUI.
Best regards,
Yvan
