Perturbation Finite Element Method for Magnetostatic and Magnetodynamic Problems

Résumé

Magnetic flux distributions are calculated in magnetostatic and magnetodynamic problems via a subproblem finite element method based on a perturbation technique. An approximate finite element problem considering ideal flux tubes or ideal materials is first solved. It gives the source for finite element perturbation problems considering the flux tubes with their exterior regions, accounting thus for leakage fluxes, as well as for changes of material properties and shapes. The proposed technique aims to accurately quantify the gain given by each model refinement on both local fields and global quantities and to justify the usefulness of this refinement. It is also well adapted to parameterized analyses on geometrical and material data.
