The unsteady compressible Reynolds-averaged Navier -Stokes equations are discretized using the Osher approximate Riemann solver with fully implicit time stepping. The resulting non-linear system at each time step is solved iteratively using a Newton/GMRES method. In the solution process, the Jacobia
## Abstract When solving electromagnetic problems by finite element method, the resulting linear systems are illβconditioned when the PML absorbing layers are adopted. Traditional Krylov iterative algorithms usually converge slowly or may even stagnate. In this paper, the combination of the innerβo
In this paper a novel preconditioning strategy is presented that is designed to improve the convergence rates of the Generalized Minimal Residual (GMRES) method when applied to dense linear systems of boundary element equations of the form Hz ----c. The GMRES method is applied to the preconditioned
