Urgent About Large Eddy Simulation
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.
Re: Urgent About Large Eddy Simulation
Welcome to the club. You will have to choose your time step which will give you courant number below 1. You will have to run LES case for much longer than your URANS case. Just as a rough guide, run it times longer than URANS case. Are you at Manchester University? What are you working on and who is your supervisor?
