Urrgent: I need your assistance about LES
 

I work with Fluent 6.3.26 to simulate this case: http://cfd.me.umist.ac.uk/ercofold/d...77/test77.html The first time I launched a simulation in 2D and I had results encouraging which you can see by consulting the following address: http://www.univ-batna.dz/mecanique/j.../4/Article.pdf Note: Excuse me because the article is written in French, but you can consult the graphs. Then I launched a simulation in 3D (models: K-E Realizable and RSM) and it gave very good results. For the continuation of my work I want to use Large Eddy Simulation (LES). I require for your assistance concerning the launching of this technique because it's the first time that I use it, especially this two information: 1. Time step Size 2. Number of time step thank you in advance.
