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.

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.
