How could I active the turbulent models that didn't exist in the list.Just like des model,les model.

CHeck the manual, You must be in 3D I think, if you want to activate LES.

I don't think so,I have herad somebody have had defined 2D les....

An excerpt from http://www.fluentusers.com/fluent61/...ug/node459.htm

!! The Large Eddy Simulation model is available only for 3D cases.

to activate les model in 2d

(rpsetvar 'les-2d? #t)

yes after this yopu have to go and check in viscous model panel to activate it

interesting.

actually lot of things are not given in fluent manuals, or they are not given at the place they should be given,

i found this out while doing an acoustic tutorial, quite and odd place to find how to activate 2d les model,

hi,

can you tell me what exatly this is.I tried this in comand line .It didn't work.

thank you

balaji

it should work, before posting the message i checked it then only i put it on forum,

further by this command u should eb able to see les models in viscous panel where u enable turbulence, so here when u check that option it calculates les model

hi,

I don't know how to use this command.I put this in the command line. It came Invalid command[rpsetvar].

Thank you.

which version of fluent u r using, and make sure that you are in 2d version of fluent (i have checked this fluent 6.1. and 6.2, and it worked fine)

I am using fluent 6.1 and 2d version. If Possible please send me a tutorial which explains about this command.It will be useful for me. Sorry for taking your time.

Thank you
