Multi-Scale Simulations of Magnetic Reconnection Using Particle-in-Cell and Magnetohydrodynamics with Adaptive Mesh Refinement Technique

Abstract

We performed magnetic reconnection simulations with our simulation code. Our code is a multi-scale three-dimensional plasma simulation code in which Particle-in-Cell (PIC) method is used in a restricted region and magnetohydrodynamics (MHD) simulation is performed in the rest of a simulation box. A hierarchical mesh is used in the MHD region, which is controlled by an adaptive mesh refinement (AMR) technique. Restriction of the PIC region and the adaptively controlled mesh realize treatment both of micro-scale particle dynamics and macro-scale structure with low computational costs. In this paper, we describe methods of our simulation and results of calculations.
