The best way to obtain the information or code capabilities is to ask code vendor directly (even a feature is not in the existing version, it may be in the next version) - alternatively each code's internet site also provides some information.

Hi,

Yes it is possible to using LES and even DNS from CFX.

By using the user fortran interface it is possible to implement different subgrid scale models to perform LES.

Best Regards

Jens

Hi,

Is there anybody who implemented LES in user Fortran? And if so are you willing to share that file with the CFD community? Kind regards,

In response to your question:

C.B. Jacobsen, 1997, Ph.D. Thesis, Numerical Part, Aalborg University, Institute of Energy Technology.

He has done LES with CFX-4.2 on a combustion Chamber Flow. He used the Smagorinsky model and the mixed (Bardina) model. The (main) user Fortran routines are listed in the back of the Thesis.
