High-order localized time integration for grid-induced stiffness

We discuss two time integration techniques, aimed at overcoming local grid-induced stiffness in discontinuous Galerkin methods. A local time-stepping approach, utilizing the local properties of the scheme, is shown to work very well. Recently developed additive Runge-Kutta methods are more general and found to be promising when combined with efficient local preconditioning.
