Can anyone send me the fluent tutorial for Turbulent flow over a backward facing step in the Fluent website(http://www.fluent.com/software/studentfluent/lcfd.htm)as i dont have have any access to their website.

Hi, Did someone send you the tutorial? 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

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.

Ok, well I was able to apply for a password to acces the student library. 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

re hi i m working on compressible fluid flow, conducting plume temperature distribution of rocket engine jet deflector system. i want to calculate the temperature distribution of theexhaust gases at depth of impingement. i first want to model the domain in 2-d. can any body give me the idea, which method i have to use for this problem. the problem is not axisymmetric with engine nozzle axis, but symmetric with width axis. so im trying to first model in 2d. i want to solve the problem with laminar flow, how can i do it? waiting for some good suggestion
