The SFD method has exhibited the ability to handle strong shocks and to outper-form the FFD method at moderate viscosity. On the more difficult problems, the SFD results are not yet as good as those of the best finite difference methods. Possibly the development of special filtering techniques especially suited for the global oscillations occurring in spectral methods will change the balance.
