A posteriori correction of high-order discontinuous Galerkin scheme through subcell finite volume formulation and flux reconstruction

摘要

In this paper, we present a new limiter for discontinuous Galerkin (DG) schemes, based on subcell resolution through reconstructed flux correction, for hyperbolic conservation laws. This limitation technique is constructed by means of a subcell Finite Volume (FV) formulation. The algorithm is thus simple, and is able to retain the very high accurate subcell resolution of DG schemes.
