Parallel implementation of a PIC simulation algorithm using OpenMP

Suciu Alin, Hangan Anca, Marginean Anca, Joldos Marius, Voitcu Gabriel, Echim Marius

Annals of Computer Science and Information Systems

2020

Vol. 21

381--385

Particle-in-cell (PIC) simulations are focusing on the individual trajectories of a very large number of particles in self-consistent and external electric and magnetic fields; they are widely used in the study of plasma jets, for example. The main disadvantage of PIC simulations is the large simulation runtime,which often requires a parallel implementation of the algorithm. The current paper focuses on a PIC1d3v simulation algorithm and describes the successful implementation of a parallel version of it on a multi-core architecture, using OpenMP, with very promising experimental and theoretical results.

Charge fluctuation of dust grains and its impact on dusty wave propagation

Atamaniuk B., Żuchowski K.

Journal of Technical Physics

2003

Vol. 44, no 2

159-162

In this paper we consider the influence of dust charge fluctuations on damping of the dust-ion-acoustic waves. Fluid approximation of longitudinal electrostatic waves in unmagnetized plasmas is considered. We show that for a weak acoustic wave the attenuation depends on a phenomenological charging coefficient.
