How to do a large eddy simulation without any SGS model?

Dear Foamers,

I'd like to do a large eddy simulation without any SGS model to test the performance of several SGS models.
What is the easiest set-up on OpenFOAM for that?
Your prompt reaction will be appreciated.

How about using one of the SGS models with the model coefficient being 0? I would think that should work.

put 'laminar' in turbulence properties. Use CDS schemes.
