在这篇简短的论文中,我们正在考虑 emph{残差分布方案} (RD) 和 emph{通量重建} (FR) 方法之间的联系。我们证明通量重建可以重新构建到 RD 框架中,反之亦然。由于这种密切联系,我们能够将 RD 方案的已知结果应用到 FR 方法。在此背景下,我们提出了所考虑的 FR 方案的熵稳定性的首次演示,并展示了如何基于我们的 FR 方法构建熵稳定数值方案。同时,我们不将网格限制为张量结构或三角形元素,而是允许多边形。我们分析的关键是正确选择校正函数,我们在此提出了一种方法。
In this short paper, we are considering the connection between the emph{Residual Distribution Schemes} (RD) and the emph{Flux Reconstruction} (FR) approach. We demonstrate that flux reconstruction can be recast into the RD framework and vice versa. Because of this close connection we are able to apply known results from RD schemes to FR methods. In this context we propose a first demonstration of entropy stability for the FR schemes under consideration and show how to construct entropy stable numerical schemes based on our FR methods. Simultaneously, we do not restrict the mesh to tensor structures or triangle elements, but rather allow polygons. The key of our analysis is a proper choice of the correction functions for which we present an approach here.
