With much progress in computational techniques and increased computational power over the past several years, 2-D global magnetospheric hybrid simulations (electron fluid, kinetic ions) have become easier to perform, and even 3-D global simulations have become feasible. Thus, discontinuities, current sheets, and boundary layers that were previously only studied in isolation, can now be investigated in their proper context: in the magnetosphere in its entirety, and within the context of solar wind - magnetosphere interaction. However, care must be taken that the discontinuities such as the bow shock and the magnetopause are properly resolved. Furthermore, it is important that the required explicit resistivity (to break the frozen-in condition, enabling reconnection) is highly localized and does not affect the thickness of current sheets and other discontinuities, or dissipation at the bow shock. We have investigated the magnetospheric current layers, dayside and tail reconnection, and dissipation at the bow shock in detail. Here, we report results of our investigation with particular emphasis on questions of resolution, field solver accuracy, and the effect of models for the resistivity.
