We give the ``philosophy'''', fairly complete instructions, a sketch and examples of creating Detached-Eddy Simulation (DES) grids from simple to elaborate, with a priority on external flows. Although DES is not a zonal method, flow regions with widely different gridding requirements emerge, and should be accommodated as far as ... design an engine cycle for aircraft thesis

In the DES approach, URANS models are employed in the near-wall regions, while the filtered versions of the same models are used in the regions away from the wall, i.e., LES modelling. The LES region is normally associated with the core turbulent region where large turbulence scales play a dominant role. design and use of the simple event model
