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...
