A time integration scheme based on Taylor expansion using the higher order discontinuous Galerkin finite element method (DG-FEM) is presented. The special properties of the scheme allow for using explicit time integration. Local timestepping techniques are proposed, which are efficient whenever large ratios in element size affect the performance of global explicit time integration schemes. The algorithm is introduced, its characteristics are analyzed, and benchmarks are presented.
