Abstract The recently developed semi-Lagrangian discontinuous Galerkin approach is used to discretize hyperbolic partial differential equations (usually first order equations). Since these methods are conservative, local in space, and able to limit numerical diffusion, they are considered a promising alternative to more traditional semi-Lagrangian schemes (which are usually based on polynomial or spline interpolation). In this paper, we consider a parallel implementation of a semi-Lagrangian disconti... Title of program: sldg Catalogue Id: AEZO_v1_0 Nature of problem An approximate solution of the advection equation is computed using the semi-Lagrangian discontinuous Galerkin method. This procedure is used as the fundamental building block in a splitting based Vlasov solver.
