Outline of Final Research Achievements

We attained following results that can be used as a basis of high performance electromagnetic field analyses. (1) We developed parallel TP-EEC method, and accelerated time periodic non-linear electromagnetic field analyses for electric machines. (2) We proposed a new IC preconditioning technique in which SIMD instructions are efficiently utilized for a linear solver involved in finite element analyses. (3) We developed parallelization methods for the analysis involving the slide mesh and the one considering the motion equation. (4) We succeeded in accelerating micro-magnetics computations by using H-matrices and parallel processing. (5) We developed a software framework to efficiently execute many electromagnetic field simulations on a parallel computer.
