A 3D Hall MHD simulation code (NRLHALL3D) has recently been developed at the Naval Research Laboratory. The 3D Hall MHD equations are solved in conservative form using a finite-volume scheme. The hydrodynamic variables in a cell are updated by calculating fluxes across the cell interfaces. The fluxes of mass, momentum, and energy across cell interfaces are calculated by integrating a Boltzmann-like distribution function over velocity space. The novel feature of the method is that the distribution function incorporates most of the electromagnetic terms. In addition the ideal MHD electric field is also calculated using the Boltzmann-like distribution function. The Hall electric field is calculated by upwinding the magnetic field using the Hall drift velocity. The code has been benchmarked against the Brio-Wu shock problem, and correctly describes whistler waves and high frequency magnetic drift waves (i.e., KMC waves). The code will be described in detail, test problems will be discussed, and applications to magnetic reconnection will be given. Research supported by NASA
