I can't get access either since I am using Fluent through my university... I am working on a backward facing step and am wondering if I chose correctly my outlet, I used pressure-outlet. What do you think? Thanks Dominique

 November 20, 2006, 13:50 Re: Fluent tutorial for turbulent flow #3 Jenner Guest   Posts: n/a No one send me that file.I also use fluent through university.I just started with velocity inlet and pressure outlet.My solution is not converging at all.So i am going to try with Coarse mesh with Std k-e model and standard wall function.Previously i was using a big flow domain and a fine mesh.

I can send you the pdf file once I can download it. I found that the Stnd K-E Model doesn't work very well for this geometry. Based on litterature, it seems that K-E RNG, Enhanced Wall Treatment is the best model to use. Also, you might want to try changing your under-relaxation factors (in Solve-Controls) to get it to converge. Good luck Dominique
