| Research Abstract |
In this research, we develop several fast linear solvers based on multigrid methods, which is effective to large-scale computation, to establish a high performance electromagnetic analysis software utilized in the development and design of various electrical equipment. The main results are the devisal and development of algebraic multigrid solvers for electromagnetic edge-element analysis, a parallel multigrid solver that enable a large-scale analysis involving more than 0.8 billion degrees of freedom, and the folded preconditioning technique that is effective to apply iterative solvers to singular systems of equations.
