A dataset for non-reflecting boundary conditions in the context of the discontinuous Galerkin method

This is a dataset for computational work investigating non-reflecting boundary conditions (NRBCs). The framework used is based on a high-order nodal discontinuous Galerkin method. The flow is described by the two-dimensional non-linear Euler equations. <br><br>The data explores the efficacy of different NRBCs, mainly: perfectly matched layers (PML), sponge layers, supersonic layers, Riemann-extrapolation methods and a new polynomial-correction (PC-)Navier-Stokes charactestic boudnary condition (NSCBC) approach. Additionally, hybrid methods also are used, by combining some of these methods together (refer to folder name). <br><br>Finally, the configuration file for generating each of these datasets is included, per folder.<br>
