Discrete representation of the model geometry with a boundary-fitted grid In a typical electrostatic PIC simulation, for each time step: 1. The charge density ρ (r , z ) is obtained by a bilinear weighting of the particles to the 2. spatial curvilinear grid (Seldner & Westermann, 1988). G G ρ (r , z) is used in Poisson’s equation to solve for the electric field E = −∇u . 3. Ez and Er are bilinearly weighted back to each particle position in order to determine the force on each particle. The Newton equations of motion (2) are used to advance the particles to new positions and velocities.
