In principle, if the SGS viscosity vanishes everywhere then it is plausible to assume the LES solution as a DNS one. However, you probably know that the static Smagorinsky model is arbitrarily...

I suggest to check for RMS, spectra and zero order statistics as average profiles of velocity. TKE can be also an indication. The SGS viscosity is dependent on the arbitrary choice of the value of...

The quality of an LES solution can not be assessed by the SGS viscosity. Other more relevant quantity must be considered (RMS, spectra, etc.). Furthermore, LES can be performed with many other SGS...
