Finite Element Difference Schemes for Electro- and Magnetostatics

摘要

Two versions of variational-difference method for solving inhomogeneous problems with curved material boundaries on regular hexahedral grids are developed. The solution is at least as accurate as in the finite element method on irregular geometrically conforming meshes but the data structures are as simple as in finite difference schemes. The proposed approach combines the ideas of the Generalized Finite Element -
