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