This work will investigate the details of how the plasma transported by the solar wind interacts with the plasma inside the magnetosphere near the dayside magnetopause. The study will use semi-global, three-dimensional hybrid simulations in which the electrons are treated using a fluid approximation, but the ions are treated using a kinetic particle description. The 3-D simulations will provide a study of the magnetopause with more realistic boundaries than have been studied in the past. Shear flow, curvature of the boundary, and coupling of boundaries and the motion of boundaries will all be included. The regions of study will include the bow shock, the magnetosheath and the magnetopause.

这项工作将调查的细节，如何通过太阳风传输的等离子体与磁层内的等离子体相互作用的向阳侧磁层顶附近。 这项研究将使用半全球，三维混合模拟，其中电子处理使用流体近似，但离子处理使用动力学粒子描述。 三维模拟将提供一个更现实的边界比过去研究的磁层顶的研究。 剪切流、边界曲率、边界耦合和边界运动都将包括在内。 研究区域将包括弓形激波、磁鞘和磁层顶。
