LES & DES turbulence models

April 13, 2007, 06:32

Just wondering if anyone knows if the large eddy simulation and detached eddy simulation turbulence models are available on the CFX package and where they can be found. or the best turbulence model to use with regards to analyzing the ahmed body. any advice would be most useful. thank you.

CFX supports LES/DES/SST-SAS.

Search for these strings in the help file.

Hi,

You also need an advanced turbulence modelling license to access these options. If you have a basic CFX license you will not have these options.

LES is in the basic solver now, just DES and SAS need the extra license.

LES and DES are working in Transient simulation only. Once you set the simulation to transient, just click on the ... box in Fluid Models and you will see LES turbulence model.

Hope this hepl.
