A discontinuous finite element method was employed for the computation of unsteady and steady flows with shocks without using spatial limiters. The results obtained show that the spatial limiting can indeed be avoided, and that high accuracy solutions with sharply resolved discontinuities can be obtained. Since the range of possible applications has not been completely clarified, it is planned to extend the analysis theoretically and by numerical experiments, with the aim to understand the underlying time relaxation limiting approach.
