汪德灌教授那本 计算水力学书后的 perisiman 隐式差分法源代码的 c++版本，我是在fortran代码中改过来的，书中的fortran代码有错误， 请较高人才得以突破 这个东西应该比较有用的吧， 尤其对刚接触这方面知识的 注释很详细哦 而且有输入文件(Professor Wang Deguan that the calculation of hydraulics perisiman after the implicit difference method source code c++ Version, I was changed from fortran code, and the book fortran code error, please talents to break with this higher things you should be more useful, especially for刚接触this regard very detailed knowledge of the Notes and the input file Oh)

the structure of the DG-FEM is very similar to that of the finite element method (FEM), there are several fundamental differences. In particular, the mass matrix is local rather than global and thus can be inverted at very little cost, yielding a semidiscrete scheme that is explicit. Furthermore, by carefully designing the numerical flux to reflect the underlying dynamics, one has more flexibility than in the classic FEM to ensure stability for wavedominated problems. Compared with the FVM, the DG-FEM overcomes the key limitation on achieving high-order accuracy on general grids by enabling this through the local element-based basis
