Application of Grid-Free Kinetic Model to Collisionless Sheath

In this work we present a grid-free hierarchical treecode, developed for simulation of bounded plasmas. The code follows both electrons and ions dynamics, resolving 1 spatial and 3 velocity coordinates. The code was applied for the simulation of a magnetized collisionless plasma in front of a material wall. The results obtained are in very good agreement with those of Particle-in-Cell simulation.
