Class
    Foam::LESModels::kOmegaSSTDES
 
Description
    Implementation of the k-omega-SST-DES turbulence model for
    incompressible and compressible flows.
 
    DES model described in:
    \verbatim
        Menter, F. R., Kuntz, M., and Langtry, R. (2003).
        Ten Years of Industrial Experience with the SST Turbulence Model.
        Turbulence, Heat and Mass Transfer 4, ed: K. Hanjalic, Y. Nagano,
        & M. Tummers, Begell House, Inc., 625 - 632.
    \endverbatim
 
    Optional support for zonal filtering based on F1 or F2 is provided as
    described in the paper.
 
    For further details of the implementation of the base k-omega-SST model
    see Foam::kOmegaSST.
