AFD-Illinois hosts and maintains a series of general relativistic magnetohydrodynamic (GRMHD) and general relativistic radiative transfer (GRRT) codes. We provide brief overview of how several codes work and document their output formats on this wiki.

codes

• ipole — a polarized GRRT code that can be used to produce simulated images from GRMHD fluid data. original paper.
• iharm3d (documentation forthcoming) — a second-order explicit shock-capturing scheme for GRMHD simulation in station spacetimes. original paper.
• KHARMA, fast HARM implementation for GPUs and CPUs, with AMR tooling.
