A Numerical Method for General Relativistic Magnetohydrodynamics [PDF]
The Astrophysical Journal, 2003 This paper describes the development and testing of a general relativistic magnetohydrodynamic (GRMHD) code to study ideal MHD in the fixed background of a Kerr black hole. The code is a direct extension of the hydrodynamic code of Hawley, Smarr, and Wilson, and uses Evans and Hawley constrained transport (CT) to evolve the magnetic fields.

The physics of non-ideal general relativistic magnetohydrodynamics [PDF]
Monthly Notices of the Royal Astronomical Society, 2021 ABSTRACT We consider a framework for non-ideal magnetohydrodynamics in general relativity, paying particular attention to the physics involved. The discussion highlights the connection between the microphysics (associated with a given equation of state) and the global dynamics (from the point of view of numerical simulations), and ...

Numerical Hydrodynamics and Magnetohydrodynamics in General Relativity [PDF]
Living Reviews in Relativity, 2008 This article presents a comprehensive overview of numerical hydrodynamics and magneto-hydrodynamics (MHD) in general relativity. Some significant additions have been incorporated with respect to the previous two versions of this review (2000, 2003), most notably the coverage of general-relativistic MHD, a field in which remarkable activity and progress
