3-Dimensional MHD Simulation of Solar Wind-Magnetosphere Interaction Computer simulation codes, simulation data of the solar wind-magnetosphere interaction obtained by a 3-dimensional global MHD model, and information on use of the supercomputer. As contents, three dimensional magnetohydrodynamic (MHD) codes (codes for the computer with small memory, vector parallel codes and scalar parallel codes for the scalar parallel supercomputer), graphic data of the three dimensional global MHD simulation of the solar wind-magnetosphere interaction, animation movie, three dimensional visualization (VRML: Virtual Reality Modeling Language), computer processing capability for the MHD simulation model, methods and example to use HPF (High Performance Fortran) and MPI (Message Passing Interface) in the MHD model. A three-dimensional global magnetohydrodynamic (MHD) simulation of the interaction between the solar wind and the Earth's magnetosphere was presented for several solar wind and interplanetary magnetic field (IMF) conditions, such as a high density of the solar wind, large values of the IMF, IMF turns from northward to southward or from southward to northward. The three-dimensional MHD simulation for the IMF rotation is also presented in a format of polar plot, structure of the three-dimensional magnetic field lines, cross sectional patterns, and reconnection sites in the magnetosphere. Moreover, the MHD simulation results with high spatial resolution are demonstrated every 30 seconds when the IMF changes its orientation to the north-south direction. The Earth's magnetospheric structure with no symmetric plane is shown for the dipole tilt when the IMF By and Bz components exist. Response of the earth's magnetosphere is also demonstrated when the satellite observation is used as input of simulation. It gives a physical simulation model and contributes to a fundamental research of the international space weather program. |
