Alternating-order interpolation in a charge-conserving scheme for particle-in-cell simulations
نویسنده
چکیده
We discuss the interpolation of the electric and magnetic fields within a charge-conserving Particle-In-Cell scheme. The choice of the interpolation procedure for the fields acting on a particle can be constrained by analyzing conservation of the energy and the particle generalized momentum. The better conservative properties are achieved, if the alternating-order form-factor is used for interpolation, which combines the lower-order and higher-order interpolation from integer and semi-integer points of a staggered grid. This approach allows us to significantly improve both the quality of results and the computational efficiency for the charge conserving scheme. © 2012 Elsevier B.V. All rights reserved.

Particle-in-Cell (PIC) methods are a well-established first-principle model that can provide a kinetic description of a plasma by following trajectories of an ensemble of charged particles in self-consistent electromagnetic fields. To the extent that quantum mechanical effects can be neglected, the PIC model makes no physics approximations and is a key tool in the study of plasma physics. The f...

متن کاملHigh-accuracy alternating segment explicit-implicit method for the fourth-order heat equation
Based on a group of new Saul’yev type asymmetric difference schemes constructed by author, a high-order, unconditionally stable and parallel alternating segment explicit-implicit method for the numerical solution of the fourth-order heat equation is derived in this paper. The truncation error is fourth-order in space, which is much more accurate than the known alternating segment explicit-impli...
