Analysis of relativistic hydrodynamics in conservation form
Philippos Papadopoulos, Jose A. Font
Formulations of Eulerian general relativistic ideal hydrodynamics in conservation form are analyzed in some detail, with particular emphasis to geometric source terms. Simple linea…

Numerical simulations of relativistic wind accretion on to black holes using Godunov-type methods
Jose A. Font, Jose M. Ibanez, Philippos Papadopoulos
We have studied numerically the so-called Bondi-Hoyle (wind) accretion on to a rotating (Kerr) black hole in general relativity. We have used the Kerr-Schild form of the Kerr metri…

Numerical hydrodynamics on light cones
Jose A Font, Philippos Papadopoulos
Characteristic methods show excellent promise in the evolution of single black hole spacetimes. The effective coupling with matter fields may help the numerical exploration of impo…
