Abstract
This paper describes large-scale analysis for high frequency electromagnetic field by the finite element analysis of Maxwell equations including the displacement current. A stationary Helmholtz equation for the high frequency electromagnetic field analysis is solved taking an electric field and an electric scalar potential as unknown functions. Domain decomposition methods enable the acceleration of the solution to large-scale analysis problems. Hierarchical domain decomposition method (HDDM) is employed as a parallel solver based on the iterative domain decomposition method. A whole body cavity resonator: TEAM Workshop problem 29 is used as a numerical example to verify the accuracy of our analysis. Numerical examples demonstrate that the developed method can compute large-scale problems over 10 million unknowns.
