Outline of Final Research Achievements

Through the development of multi-hierarchy interlocked simulation model, in which simulation domain is divided into multiple hierarchies according to governing physical processes and physics in each hierarchy can be solved simultaneously by an interlocking method, simulation research has been promoted aiming at clarification of the following physical tasks; (1) triggering mechanism of an anomalous resistivity, (2) structure transition and energy conversion processes, (3) cross-hierarchy phenomena controlled by magnetic reconnection in fusion plasmas. Especially, important findings has been obtained in the researches of structure formation process in the earth magnetosphere, merging process of fusion plasmas controlled by magnetic reconnection, and so on.
