LES Model

I am using Dynamics Large Eddy model on a simple structured Cartesian grid. I use staggered grid with pressure inside the cell and velocities on the faces. Related to LES, is there any difference to allocate the vraiables (Cs, turbulent viscosity, etc. ) in the "centre of cells" or "vortices"? Thanks

JK, Thanks for reply. But I would like to know, what is difference, if we set the turbulence variable on the center of cells, or on the grid point? And where I must put the these variables? In the center or on the grid points?

I've written LES code with velocities on faces, pressure at cell center and turbulence variables at cell vertices. It worked for me.
