We perform a geomagnetic event simulation using a newly developed magnetohydrodynamic with adaptively embedded particle-in-cell (MHD-AEPIC) model to study by solving the magnetotail reconnection physics better, what’s the influence on the simulation results at multiple physical scales. We also present the Hall MHD and ideal MHD simulation results of the same event for comparison. For the global scale features, three models produce very close SYM-H and SuperMag Electrojet Index (SME), which indicates the global magnetic field configurations from three models are very similar to each other. For the mesoscale feature, the MHD-AEPIC and Hall MHD models can produce tailward and earthward fluxropes. However, there is no fluxrope generated at the near-earth current sheet by the ideal MHD model. For the electron scale feature, the MHD-AEPIC can produce a crescent shape distribution of the electron velocity space at the electron diffusion region which is agreed with the MMS observation. The kinetic feature is not available in either Hall MHD or ideal MHD model.
