Application of adaptive mesh refinement to PIC simulations in heavy ion fusion

An end-to-end simulation of a Heavy-Ion Fusion driver is very challenging due to the wide range of scales involved. We have merged the Particle-In-Cell and the Adaptive Mesh Refinement (AMR) methods and have applied it to the simulation of HIF beam sources. We describe our past progress and present our recent implementation of automatic AMR in WARP.
