Key Points

To review computational modeling frameworks developed to overcome the multiscale challenges of simulating plasma magnetic reconnection.
Evaluated critical theoretical assumptions and numerical techniques across fluid, kinetic, and hybrid plasma frameworks.
Surveyed models including standard and Hall magnetohydrodynamics (MHD), kinetic particle-in-cell (PIC), Vlasov approaches, embedded PIC methods, and the Rice Convection Model (RCM).
Identified that no single numerical model resolves all spatio-temporal scales simultaneously due to extreme computational constraints in multiscale reconnection physics.
Demonstrated that macroscopic fluid formulations successfully capture large-scale plasma topology, while kinetic and coupled PIC techniques are required to resolve small-scale dissipation zones and particle acceleration.

Methodological review reveals multiscale modeling approaches across plasma physics regimes, highlighting the necessary trade-offs for simulating magnetic reconnection.

Abstract

Simulations have played a critical role in the advancement of our knowledge of magnetic reconnection. However, due to the inherently multiscale nature of reconnection, it is impossible to simulate all physics at all scales. For this reason, a wide range of simulation methods have been crafted to study particular aspects and consequences of magnetic reconnection. This article reviews many of these methods, laying out critical assumptions, numerical techniques, and giving examples of scientific results. Plasma models described include magnetohydrodynamics (MHD), Hall MHD, Hybrid, kinetic particle-in-cell (PIC), kinetic Vlasov, Fluid models with embedded PIC, Fluid models with direct feedback from energetic populations, and the Rice Convection Model (RCM).
