Iharm3D是一个开源的C代码，用于使用理想广义相对论磁流体动力学（GRMHD）模拟任意静态时空中的黑洞吸积系统。它是在Gammie等人（2003）中概述的HARM（“高精度相对论磁流体力学”）算法的实现，并在McKinney&Gammie（2004）和Noble等人（2006）中概述了更新。该代码最直接来自Ryan等人（2015），但删除了辐射传递部分。HARM是一种守恒型有限体积格式，用于求解任意坐标系下的理想GRMHD（双曲型偏微分方程组）。
Iharm3D is an open-source C code for simulating black hole accretion systems in arbitrary stationary spacetimes using ideal general-relativistic magnetohydrodynamics (GRMHD). It is an implementation of the HARM ("High Accuracy Relativistic Magnetohydrodynamics") algorithm outlined in Gammie et al. (2003) with updates as outlined in McKinney&Gammie (2004) and Noble et al. (2006). The code is most directly derived from Ryan et al. (2015) but with radiative transfer portions removed. HARM is a conservative finite-volume scheme for solving the equations of ideal GRMHD, a hyperbolic system of partial differential equations, on a logically Cartesian mesh in arbitrary coordinates.
