Primal Macro-Projective Integration Method for Multi-Scale Plasma Simulation

Abstract

We discuss a simulation framework, called Equation-Free Projective Integration (EFPI), which can perform macro-simulations while still taking the effects of micro-scale physics into account. In particular, we propose a primal-EFPI scheme to simulate the ion sound wave paradigm, which includes nonlinear wave steepening and kinetic effects in a plasma.
