Eccentricity reduction of binary neutron star initial data with the entropy based flux limiting scheme
Georgios Doulis, Sebastiano Bernuzzi, Wolfgang Tichy
The construction of high-resolution shock-capturing schemes is vital in producing highly accurate gravitational waveforms from neutron star binaries. The entropy based flux limitin…
Entropy based flux limiting scheme for conservation laws
Georgios Doulis, Sebastiano Bernuzzi, Wolfgang Tichy
The entropy based flux-limiting (EFL) scheme is a novel approach designed to accurately resolve shocks and discontinuities in special and general relativistic hydrodynamics. By ada…
