This paper introduces three techniques that the authors have recently proposed in the area of iterative solvers. The first is a new framework of an explicit and implicit error correction method for error correction in linear iterative solvers. The second technique is folded preconditioning, a technique based on an important theorem about Krylov subspace methods applied to a singular linear system. This technique can reduce redundant unknowns of a singular linear system without any degradation of convergence. The third is A-phi block preconditioning. This technique is a type of folded preconditioning and is specially designed for finite element electromagnetic field analyses. A numerical test confirms that the proposed method reduces computational time for a high-frequency electromagnetic field problem by 45%.
