Abstract :
In this paper, we investigate the three most robust finite element-based domain decomposition methods for modeling of large phased arrays. They are (1) the conformal dual-primal finite element tearing and interconnecting method with one or two Lagrange multipliers, (2) the nonconformal dual-primal finite element tearing and interconnecting method with two Lagrange multipliers, and (3) the nonconformal optimized Schwarz method based on cement elements.
