Abstract :
This paper presents a new preconditioned dual-primal non-overlapping domain decomposition method for the finite element solution of three-dimensional large-scale electromagnetic problems. Fast convergence performance is achieved with the aid of (1) a higher-order transmission condition; (2) a global coarse space correction; and (3) an algebraic preconditioner. Several numerical examples with perfectly matched layer mesh truncations are presented to demonstrate the validity and the capability of this method.
