ANALYZING METHOD BY INFINITE ELEMENT METHOD AND DEVICE THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide an analyzing method by an infinite element method capable of saving an arithmetic quantity and a using memory and precisely analyzing when a material constant is not continuous such as the presence of a magnetic body ion a node element infinite element method using vector potential. SOLUTION: When a discontinuous face where a material constant (e.g. permeability) discontinuously varies exists between divided elements in the case such as including a magnetic core 31 within a space in analysis by the infinite element method dividing an analyzing object into infinite elements and analyzing them. At least one layer of new elements 35 are added in the normal direction of the discontinuous face at the position of the discontinuous face of the material constant to analyze by the infinite element method.
