2024年7月30日 · This eight-week online course will teach you how develop electrostatic plasma simulation codes using the Particle In Cell (PIC) method. PIC is a popular numerical approach used to simulate plasmas, rarefied gases, and other …

2003年1月1日 · This chapter serves as a tutorial introduction to the field of particle-in-cell (PIC) simulation of plasmas. The full particle version of these models, in which both the electrons and ions are treated as particles, makes no approximations to the basic laws of mechanics and electricity and magnetism, and thus the full range of collisionless ...

2023年3月2日 · The Particle-in-Cell (PIC) method has a long history dating back to the 1950s. The method was first developed by computational physicists who were interested in simulating the behavior of plasmas in fusion reactors.

2013年10月17日 · In 1957, Francis H. Harlow with Los Alamos Scientific Laboratory developed the Particle-In-Cell (PIC) method that centered on manipulating particles that represented a small mass. Each particle had a variable for position, mass, and species information for its placement on an Eulerian 2D mesh.

The original method (known as Particle-In-Cell (PIC)) was developed by Harlow (1955) and by Evans and Harlow (1957), and has been greatly extended by Welch, Harlow, Shannon and Daly (1966). The latter treatment is known as the Marker and Cell (MAC) method.

The electrostatic particle in cell (ES-PIC) method is introduced by developing a 3D simulation of electrons oscillating in a grounded box filled with background ions. This chapter also serves as a crash course in C++.

The core PIC algorithm involves four operations at each time step: 1) evolve the velocity and position of the particles using the Newton-Lorentz equations, 2) deposit the charge and/or current densities through interpolation from the particles distributions onto the grid, 3) evolve Maxwell’s wave equations (for electromagnetic) or solve Poisson’...

Particle-in-Cell (PIC) simulation represents a powerful tool for plasma studies having a number of advantages like the fully kinetic description of high-dimensional plasma and the ability to incorporate complicated atomic and plasma-surface interactions.
