The particle-in-cell method
In plasma physics, the particle-in-cell (PIC) method refers to a technique used to solve a certain class of partial differential equations. In this method, individual particles (or fluid elements) in a Lagrangian frame are tracked in continuous phase space, whereas moments of the distribution such as densities and … Visa mer For many types of problems, the classical PIC method invented by Buneman, Dawson, Hockney, Birdsall, Morse and others is relatively intuitive and straightforward to implement. This probably accounts … Visa mer Within plasma physics, PIC simulation has been used successfully to study laser-plasma interactions, electron acceleration and ion heating in the auroral ionosphere, magnetohydrodynamics, magnetic reconnection, as well as ion-temperature-gradient and other … Visa mer • Particle-In-Cell and Kinetic Simulation Software Center (PICKSC), UCLA. • Open source 3D Particle-In-Cell code for spacecraft plasma interactions (mandatory user registration required). Visa mer Inside the plasma research community, systems of different species (electrons, ions, neutrals, molecules, dust particles, etc.) are investigated. The set of equations associated with PIC codes are therefore the Lorentz force as the equation of motion, solved in the so … Visa mer • Plasma modeling • Multiphase particle-in-cell method Visa mer • Birdsall, Charles K.; A.

Webb15 mars 2024 · The particle-in-cell (PIC) method has been widely used for plasma simulation, because of its noise-reduction capability and moderate computational cost. The immersed finite element (IFE) method is efficient for solving interface problems on Cartesian meshes, which is desirable for the PIC method. The combination of these two … WebbThis 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 …
WebbExperience has shown that the PIC method works best with at least 16 particles per cell (i.e., a 4 by 4 array in two dimensions or 64 particles per cell in three dimensions). A smaller number of particles could be used when larger fluctuations could be tolerated (or when computing resources did not allow for a larger number, a frequent situation in the … Webb2 maj 1995 · The particle-in-cell method uses two representations of the continuum, one based on a collection of material points and the other based on a computational grid. The material points are followed throughout the deformation of a solid and provide a Lagrangian description that is not subject to mesh tangling.
Webb24 okt. 2024 · Particle-In-Cell (PIC) methods are frequently used for kinetic, high-fidelity simulations of plasmas. Implicit formulations of PIC algorithms feature strong conservation properties, up to numerical round-off errors, and are not subject to time-step limitations which make them an attractive candidate to use in simulations fusion plasmas.
