Question related Code_Saturne recommandation
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).

Re: Code_Saturne on hpc
Hello,
I have made an additional test locally on my machine. I'm asking 5 processes with 1 thread per process and when looking at my log file, I can read:
Processors/node: 6
OpenMP threads : 4
I thought I would have respectively 5 and 1.
Could someone explain me this?
Kind regards
JCo

Re: Scalars and RIJ ssg
Hello again,
I was considering that DFM would be more suitable than SGDH in case I use RIJ ssg turbulence, am I wrong on this point?
Kind regards
