Dear Sandy,
in the report you can find also the documentation for the BL flow, why don't you follow that test-case?

Hello Filippo,

I'm trying to simulate the same case of Sandy and now I'm stuck at the same point of yours, creation a homogeneous turbulence at the inlet of the duct, I'm using openfoam 3.0.x with LES and WALE as SGS model. So, if you please did you know the way to get the inlet boundary condition as homogeneous turbulence?

where the above velocity is 2m/sec and lower fluid flows with 1 m/sec.

I have successfully solved the case for 2d laminar and turbulent cases(1 equation, 2 equation model) and verified the results with FLUENT.

Now i have been trying to implement the code for Large eddy simulation, and i've got the results for FLUENT simulation(thanks to online CFD ref: http://www.cfd-online.com/Forums/flu...past-cube.html)

I am not able to give perturbation to inlet boundary condition in my code, can some one help me in giving the function that can be imposed on the inlet BC for giving some perturbation.
OR can some tell me how to give inlet boundary condition for LES for such cases??
