Abstract :
In this paper, an inner-outer flexible GMRES method is applied to analyze the electromagnetic problems with three-dimensional edge-based FEM. Our numerical simulations show that the number of iterations and CPU time used are about five times less than that with the conventional restarted GMRES method.
