Analysis of grid instabilities in particle-in-cell codes based on a meshfree approach
J. M. Finn, E. G. Evstatiev
A new method of analyzing grid, or aliasing, instabilities is described, in particle-in-cell (PIC) codes for plasma kinetic theory. It starts with a meshfree approach with …
Noise and error analysis and optimization in particle-based kinetic plasma simulations
E. G. Evstatiev, J. M. Finn, B. A. Shadwick +1
We analyze the noise in macro-particle methods used in plasma physics and fluid dynamics, leading to approaches for minimizing the total error, focusing on electrostatic models in…
Application of the phase space action principle to finite-size particle plasma simulations in the drift-kinetic approximation
E. G. Evstatiev
We formulate a finite-size particle numerical model of strongly magnetized plasmas in the drift-kinetic approximation. We use the phase space action as an alternative to previous v…
Variational formulation of particle algorithms for kinetic plasma simulations
E. G. Evstatiev, B. A. Shadwick
Common time-explicit numerical methods for kinetic simulations of plasmas in the low-collisions limit fall into two classes of algorithms: momentum conserving and energy conserving…
