Hi Can fluent solve the 2d Flitered NS (Large Eddy Simulation) equations?

Also if fluent doesn't offer 2d LES capablitites can anyone sutggest a COMERCIAL code that does.

Thanks in advance

Yes, fluent can run the LES model in 2D. However, it doesn't make much sence to do this. LES = Large Eddy Simulation = resolving the large scale turbulent eddies. These large-scale turbulent eddies are 3D by nature and if you run 2D you will not resolve them. Hence, a 2D LES simulation is not going to produce anything physical. It is just a numerical exercise that you might want to do to debug your code or something.

Hi Jonhson,

As if you say running LES for 2D is just an numerical excersize then while soving flow over cylinder by LES Model gives different results than K-epsilon.. I means LES model gives close results...though large eddies are absent or 3d in nature....can you please give some idea of same. Since I am trying to solve flow over cylinder...

use command (rpsetvar 'les-2d? #t)
LES will come in models option
LES is used for axis-symmetric geometries only
