Scientific paper

A Harten-Lax-van Leer Discontinuities (HLLD) approximate Riemann solver, which was recently developed by Miyoshi and Kusano (2005), is improved for extended magnetohydrodynamic (MHD) equations that include a background potential field, multi-component plasmas, and an arbitrary equation of state, and is applied to the magnetospheric global simulation. The resolution of the HLLD solver is as well as the standard linearized Riemann solver, but the HLLD solver is more robust and efficient than the other linearized Riemann solver. The validity and efficiency of the HLLD solver for the magnetospheric simulation is carefully examined, and it is shown that the HLLD solver is more suitable for extended MHD than the other linealized Riemann solvers.
