i gave my first cell height is 0.0020 accordingly with roughness measurements (0.0019) Ks< first cell height. Can i run this model in LES. ( Model height is 0.7 , width is 0.15m and Domain height is 1.8 m all are accordingly with wind tunnel test section).
Its is possible to run a terrain profiles simulation in ANSYS Fluent, accordingly with roughness parameters limitation (Ks< first cell height) in LES?
Could you expand your question with the details of your problem? Why are you working with LES in such a problem?
Thanks for rsponding Maria Denaro,
Actually, I scaled my building model (1;300). According with that i changes my aerodynamic roughness (0.0019). If i calculate Ypluse it comes nearly 100. But LES is requries more fine (Ypluse 1 to 5). I am doing transient simulation for furter stuides LES validation also requiers.
If you are not able to refine enough the grid, then you shoulc consider the chance to adopt a suitable wall model function wherein roughness is included.
