Force-Free Electrodynamics (FFE) describes a particular regime of magnetically dominated relativistic plasmas, which arises on several astrophysical scenarios of interest such as pulsars or active galactic nuclei. In this article, we present a full 3D numerical implementation of the FFE evolution around a Kerr black hole. The novelty of our approach is three-folded: i) We use the “multi-block” technique [1] to represent a domain with S2 × R+ topology within a stable finite-differences scheme. ii) We employ as evolution equations those arising from a covariant hyperbolization of the FFE system [2]. iii) We implement stable and constraint-preserving boundary conditions to represent an outer region given by a uniform magnetic field aligned or misaligned respect to the symmetry axis. We find stationary jet solutions which reach equilibrium –through boundary conditions– with the outer numerical surface. This is so, even when the outer boundary is located very close to the central region (i.e. rout ∼ 10M ). These numerical solutions reproduce most of the known results for analogue astrophysical settings. info:eu-repo/semantics/submittedVersion Fil: Carrasco, Federico León.
