Abstract
This work is concerned with the introduction of a new numerical scheme based on the discontinuous Galerkin (DG) method. We propose to follow the methodology of higher order finite volume schemes and introduce a reconstruction operator into the DG scheme.
This operator constructs higher order piecewise polynomial reconstructions from the lower order DG scheme. Such a procedure was proposed already in Dumbser et al. (2003) based on heuristic arguments, however we provide a rigorous derivation, which justifies the increased order of accuracy.
Numerical experiments are carried out.
