変形二次六面体要素を用いた保存則法による電磁界解析  [in Japanese] Using Pseudo Second Order Hexahedron Element Electromagnetic Field Analysis By Preservation Rule Method  [in Japanese]

The method based on preservation rule (FPM) is simple form and high accuracy in comparison with FEM. This paper discusses FPM using pseudo second order hexahedron element. Form viewpoint of the primary and adjoining points in partial area of the element, pseudo second order element is introduced. The nature of local matrix derived from this element is similar the local matrix of first order element. For numerical results of 3D-electnc field analysis, it is clear that errors by FPM using this element are decreased both errors by FPM and FEM using normal second order and first order elements.
