本文综述了求解高维偏微分方程的自适应稀疏网格间断Galerkin(aSG-DG)方法及其软件实现。名为AdaM-DG的C++软件包实现了aSG-DG方法,可在GitHub上获得,网址为https://github.com/JuntaoHuang/adaptive-multiresolution-DG。该软件包是能够处理一类大的高维线性和非线性偏微分方程。我们回顾了算法的基本组成部分和软件的功能,包括使用的多小波,组装的双线性算子,快速矩阵向量积的数据与层次结构。我们进一步证明了包的性能,通过报告的数值误差和CPU成本的几个基准测试,包括线性输运方程,波动方程,和汉密尔顿-雅可比(HJ)方程。
This paper reviews the adaptive sparse grid discontinuous Galerkin (aSG-DG) method for computing high dimensional partial differential equations (PDEs) and its software implementation. The C++software package called AdaM-DG, implementing the aSG-DG method, is available on GitHub at https://github.com/JuntaoHuang/adaptive-multiresolution-DG. The package is capable of treating a large class of high dimensional linear and nonlinear PDEs. We review the essential components of the algorithm and the functionality of the software, including the multiwavelets used, assembling of bilinear operators, fast matrix-vector product for data with hierarchical structures. We further demonstrate the performance of the package by reporting the numerical error and the CPU cost for several benchmark tests, including linear transport equations, wave equations, and Hamilton-Jacobi (HJ) equations.
