  • Abstract : In this work we develop a novel shock capturing procedure based on adaptive reformation of finite volume sub-cells for higher order discontinuous Galerkin method. For this we developed a sub-cell shock indicator based on Harten’s strategy to provide enhanced shock detection using just the degrees of freedom in respective mesh element. We apply this new procedure in the current state-of-the-art entropy stable discontinuous Galerkin method and demonstrate some numerical results for 1D compressible Euler equations.
