In this presentation, we will show the convergence results of the developed solver over several classical PDE examples over both structured and unstructured grids. Finally, an end-to-end learning of the hyperparameters in the DG scheme will be demonstrated to show the effectiveness of the proposed framework on advancing CFD for compressible flows with machine learning techniques.
