Research Abstract |
Massively parallel model of the 3D electromagnetic particle-in-cell code with adaptive mesh refinement has been developed and achieved high parallel efficiency (80% for 128-core parallelization) on a distributed memory system. This enables us to use much more computer resources and to perform larger-scale particle simulations. By using this code, we have conducted a large-scale 3D simulation of magnetic reconnection and found that an electron-scale electromagnetic mode is triggered in the thin current layer formed around the magnetic neutral line.
