![]() Magnetohydrodynamic With Embedded Particle-In-Cell Simulation of the Geospace Environment Modeling Dayside Kinetic Processes Challenge Event. Chen, Y., Tóth, G., Hietala, H., Vines, S.By tracing the locations of the X-lines, we find the typical moving speed of the X-line endpoints is about 70~km/s, which is higher than but still comparable with the ground-based observations. It turns out that there are usually multiple X-lines at the magnetopause. We use an algorithm to automatically identify the reconnection sites from the simulation results. The MHD-EPIC simulation produces flux ropes, and we demonstrate that some magnetic field and plasma features observed by the MMS3 spacecraft can be reproduced by a flux rope crossing event. Most variables match the observations well in the magnetosphere, in the magnetosheath, and also during the current sheet crossing. We compare the magnetic fields and the plasma profiles of the magnetopause crossing with the MMS3 spacecraft observations. ![]() In the MHD-EPIC simulation, the dayside magnetopause is covered by a PIC code so that the dayside reconnection is properly handled.
