Can anybody tell me , how to enable DES model in fluent, as i am not able to see that in viscous panel, i guess there must be some , scheme commond to do so, like (rpsetvar 'varrr? #t) or (allow-des-model) types ,

i have got the detached-eddy-simulation option through turbulence-expert and enabled the DES , but i still wonder why it is not showing that in viscous panel, there still SA is selected, anybody has any idea ?????

hi, can you tell your case i heard about les what this dteached eddy simulation for????????????

mixture of les and rans

You will not see any DES button/panel under turbulence model options. But if you plot residuals, it will show up there that you are using DES model.

okey, actually i know that it is activated but since it wasn't showing on screen and that i din't like, anyway thanks for clearification
