A Proof of the Stability of the Spectral Difference Method for All Orders of Accuracy
Spectral Difference Method Accuracy
2015/6/23
One of the most promising approaches is the
Discontinuous Galerkin (DG) method, for which the theoretical basis has been provided in
a series of papers by Cockburn and Shu [1, 2, 3, 4]. The rapid gr...
