Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>We give a short overview of an extended Discontinuous Galerkin and Spectral Difference Method using PKD polynomials on triangular grids. A corresponding exponential filter is used to avoid oscillations near discontinuous solutions and to give some stabilization for nonsmooth testcases.</p> </abstract>
