Hi all
I wanna simulate the flow around a cube by using Fluent LES . I know that it is necessary to set fluctuations at Inlet. Now I have some questions:
If I use "vortex method" to generate fluctuations at inlet, how could I give the "Number of Vortices"? (By default, the number of vortices is 190). And how this value influence the result?
By the way , the version of my Fluent is 17.2
