    Abstract

    A database of various LES and two reference DNS of homogeneous isotropic turbulence is constructed at Re λ = 50. All LES are performed with Smagorinsky or dynamic Smagorinsky modeling. Using the database information, accuracy charts are constructed, which give a global view of the error as function of important LES parameters. Moreover, as a result, ‘optimal refinement strategies’ are identified for LES. Further, the dynamic model is shown to select its own refinement trajectory. The distance of this trajectory to the ‘optimal’ refinement path is a measure for the quality of the dynamic procedure.
