Abstract

Compatible sub-gridding technique and domain decomposition method are employed to analyze a special structure of electromagnetic field problems. Compatible sub-gridding technique can improve the numerical solution precision distinctly. Meanwhile, it can reduce a lot of unknowns enormously. Furthermore, combining this compatible sub-gridding technique with the domain decomposition method (DDM), it can be used to analyze large scale and complicated structure of electromagnetic field problems. Numerical results show that it is efficient.
