Outline of Final Research Achievements |
We aimed to improve the efficiency of electromagnetic field simulation, which is used in the design and development of various electrical equipments, and studied on the development of new sparse matrix computation techniques that has never existed before. We performed research on speedup of sparse matrix linear iterative solver by eigen-/singular- vector estimation and application of geometric block diagonal preconditioning method to edge element electromagnetic field analysis, and obtained theoretical and numerical experimental results. Furthermore, we have developed a research on model reduction of a system involving a sparse matrix and obtained fruitful knowledge and theoretical results.
