Hello everybody,

I have simulated turbulent air flow in a complex geometry at the past and I had a lot of problems concerning the values for the k-epsilon model. I am attaching a link that I found after hours searching at the internet that it was extremely helpful for my case. Maybe this can give you more insight concerning your matter. My results were far better than I expected!

Hi Nicolas,

Why are you mentionning a ref point for pressure in the transportProperties file?
I thought it was in the fVsolution file?

regards,

changing the tolerance and relTol in the fvSchemes. Even if simpleFoam is steadyState, I've also changed the deltaT according to this document.
I've checked the U_mag in Paraview after 300it (just before leaving the office) and once again the flow seemed to be laminar. I haven't look at the stability with probe point.
That's something wrong with my case, but I don't know where ...

I'll try with a basic elbow tomorrow. This one is a bit elaborate (or do we say chased ?): that's why I can't share it.

this link is broken can you please update with a new link to the PDF?
