However I saw a large difference between a spectral element and fvm for capturing structures and other features. @User turbulence is local, then either method (FVM/SEM/FR/DG), may be able to resolve turbulence. The problem resides on HOW the non linear term in NS is "discretized", and in FV whether you are respecting the Peclet limit for the linear schemes.
