Uregent LES model
 
I want to simulate flow over a wavy wall and I chose this case:

Separ
ated Turbulent Flow Over a Wavy Wall
DNS by Maaß and Schumann


http://cfd.mace.manchester.ac.uk/cgi...html&1&0&0&0&0

First, I compared the following models of the commercial code ANSYS Fluent (K-E, RNG K-E and RSM) in 2 and 3D and I had good results.

Second, I have used unsteady
Realizable K-E (3D)
and I had good results too.

For the continuity of my work, I want to run a simulation with LES model to see the effect of wave amplitude (various range of the wave amplitude).

I have build a geometry with more grid density near the walls.

Can you help me run the LES model, knowing that this is the first time I use it.

Thank you in advance.

I am interested in this work too.

Thank you for your response, have you any tutorial obout LES method with Fluent please or any idea about my problem?

Any help please, it's very urgent.

Sorry I can't be of any help as I have no experience in this field. But I know some one who has recently done a simulation on cylinder with LES. I will try to forward his email id to you by tomorrow.
