| Outline of Final Research Achievements |
To extend the MHD simulation code, the development of two-fluid plasma simulation was proceeded. The non-physical oscillations were found in the execution test then the simulation code needs to be reviewed including the equation system. In the explicit method the time step is defined by the light speed thus the introduction of implicit method was considered. However, the advantage of introduction was much small since the time step in the implicit method needs to be small to see the dynamic time evolution phenomena. To perform the calculation rapidly, the new communication model was introduced to the simulation, which achieved good performance in the massively parallel system.
