DetachedEddySimulation class is used for running hybrid RANS-LES simulations "It is supported for both SpalartAllmaras and kOmegaSST turbulence models, with and" "without AmplificationFactorTransport transition model enabled."
TurbulenceModelControls class specifies modeling constants and enforces turbulence model behavior on a zonal basis, as defined by mesh entities or boxes in space.
