Journal ArticleDOI
Direct implicit large time-step particle simulation of plasmas
TL;DR: In this article, an implicit method for solving the set of coupled particle and field equations arising in particle-in-cell plasma simulation is described in detail, motivated by the desire to study efficiently low-frequency, longwavelength plasma phenomena using a large time step.
Journal ArticleDOI
Three-dimensional particle simulation of heavy-ion fusion beams
TL;DR: Friedman et al. as discussed by the authors developed warp, a multidimensional particle simulation code, which combines features of an accelerator code and a particle-in-cell plasma simulation.
Journal ArticleDOI
Implicit time integration for plasma simulation
TL;DR: In this article, the stability and accuracy of implicit time integration schemes for plasma particle-in-cell simulation and the synthesis of new algorithms have been undertaken to increase the size of the time step, and thereby extend the applicability of kinetic plasma simulation.
Journal ArticleDOI
Novel methods in the Particle-In-Cell accelerator Code-Framework Warp
TL;DR: The Particle-In-Cell (PIC) Code-Framework Warp as discussed by the authors was developed by the Heavy Ion Fusion Science Virtual National Laboratory (HIFS-VNL) to guide the development of accelerators that can deliver beams suitable for high energy density experiments and implosion of inertial fusion capsules.
Proceedings ArticleDOI
The WARP Code: Modeling High Intensity Ion Beams
TL;DR: The Warp code, developed for heavy‐ion driven inertial fusion energy studies, is used to model high intensity ion (and electron) beams, and is at the forefront in the use of the computational technique of adaptive mesh refinement.
