OpenPixi

Description

OpenPixi is an open Particle-In-Cell (PIC) simulator. It simulates the motion of a large number of charged particles in an electro-magnetic background. Currently the simulation supports tracking thousands of particles in constant electric, magnetic, and gravitational fields. Support for dynamic relativistic particles and fields is in preparation.

OpenPixi is being developed in Java, with an educational aspect in mind. As such, it is possible to interact with the plasma in a live Java applet.

Google Summer of Code 2013

OpenPixi participates in the Google Summer of Code 2013 as part of the group of Computational Science and Engineering at TU Wien.
