General Question about Mixing Parameterization


I have just started using CROCO and have a few general questions regarding mixing parameterization. When the GLS sub-grid turbulence model is used (e.g., define GLS_MIXING), do the variables Akv_Bak and Akt_Bak in specify values of background viscosity and diffusivity or should they be set to zeros?

Also, I notice that there is a GLS_MIXING_3D option that is recommended for NBQ simulations in the tutorial. I would like to know if the '3D' label means the turbulence model yields turbulence parameters in both vertical and horizontal directions.

Thanks! Guangyu
