Re: how to use LES
Hi,
by doing LES you are calculationg the large scale turbulence directly (that's why it's called large eddy simulation) and you are only modeling the "subgrid scale". Turbulence ist 3 dimensional phenomenon and bacause most of the turbulence is calculates directly with LES (and is not modelles like with RANS) you have to do 3D calculations... regards michael |
