Abstract

A multiscale algorithm is developed in this study in which the ideal MHD equations is coupled with a two-fluid or a fully kinetic model to correctly model magnetic reconnection that is a common phenomena in the magnetosphere and in laboratory plasmas. In this approach, special Riemann solvers are constructed in such a way as to minimize spurious reflections at the model interface. The proposed method is validated on several test cases of waves propagating through the model interface.
