A parallelized two-dimensional full particle-in-cell (PIC) simulations with an adaptive mesh refinement (AMR) technique for the interaction of solar wind with kinetic scale magnetosphere around a magnetic sail are conducted. For multi-scale simulations, the newly developed AMR-PIC code has a method to modify the grid size and time step interval of computational domain in the midst of the simulations temporally and locally. In the simulation results under the typical working condition introducing the AMR technique, it is shown that the direction of interplanetary magnetic field depend strongly on the magnetospheric configuration including electron dynamics and Alfven bow shock structure. Although more validation studies are needed, the AMR-PIC code shows the worth of development for multi-scale simulations.
