Dear Reza, OPENFOAM is a good choice especially regarding its many forums and users. but you may want to check a newly released "SU2" , developed by stanford U.

Dolfyn is another option, it is less famous but it is written in fortran and based on the book "Computational methods for fluid dynamics; by Ferziger and Peric"

Dear Mohsen,

Thanks for your help.

I agree with Mohsen, OpenFOAM is in my opinion is more suitable to turbulence simulation by LES. In my opinion this is true both for the kind of numerical discretization adopted in the LES solvers than for the variety of SGS modeling available.

I was involved as a member of LESinItaly project in testing the accuracy of both numerical discretization and the performance of the LES module available in OpenFOAM.

The results were compared with other obtained with several commercial and open source code provided by other research groups involved in the project.

The case study adopted, was the simulation of a turbulent flow in a plane channel forced with a constant pressure gradient. The results were encouraging both for first and second order statistics of turbulent velocity field. The combined effect of the local truncation error of the numerical scheme plus the effect of the implicit grid filtering produced not so much artificial dissipation on the large scales velocity field.

Below I post the link to the paper containing the aforementioned results,

Dear Andrea,

Thanks for the useful comments and the paper.

I want to capture turbulent fluctuations with high resolution near the wall region. It seems that OpenFOAM is good for this.

Sincerely,

Reza

Dear all, Does OpenFoam only run on Linux?

Dear Hamed

To my recollection I believe so. but I suggest to check Openfoam official website
