Description/Abstract
The paper offers a comparative study of numerical methods of analysis of electromagnetic fields. The focus is on the Finite Element Method (FEM) and Finite Integration Technique (FIT), but with the cell and equivalent network approaches also considered. It is shown how the approximate integrals describing coefficients of the FEM need to be derived for a mesh with parallelepiped elements to achieve consistency with FIT equations. The equivalence of FEM and FIT formulations for a triangular mesh in 2D is highlighted. The TEAM Workshops Problem No. 7 is used as an example for numerical comparisons. Edge values of magnetic vector potential A and nodal values of electric scalar potential V are used throughout.
