Resum

This talk will look at ENO and WENO schemes of higher than second order in comparison with TVD methods (both slope and flux limited methods, such as WAF) when applied to ultrarelativistic hydrodynamics. I will discuss the use of different flux solvers (exact, Roe, Marquina and Lax-Friedrichs) and some AMR calculations.I will show various shock tube tests (including some applied to the full relativistic hydro equations). I'll also show an application of these schemes to gravitational collapse of a density perturbation in an expanding FRW universe.
