Iterative solution techniques for unsteady flow computations using higher order time integration schemes

摘要

In this paper iterative techniques for unsteady flow computations with implicit higher order time integration methods at large time steps are investigated. It is shown that with a minimal coding effort the standard non-linear multigrid method can be combined with a Newton-Krylov method leading to speed-ups in the order of 30%.
