High-Order Compact Schemes for Plasma Wave Simulation.

摘要

A high-order finite-difference code has been developed with the ability to simulate waves in plasmas coupling Maxwell Equations with fluid species equations. Originally developed to examine the radio blackout problem, the code utilizes 6th-order finite-differences with 10th-order filters in space and 4th-order Runge-Kutta in time in order to minimize the number of grid points while retaining the fidelity of the solution. The code also uses multiple overlapping grids allows for solving complex configurations in parallel.
