摘要:

有限体积元方法引入了新的超收敛结构,使我们可以自由选择超收敛点。建立了广义正交条件和改进的M-分解(MMD)技巧,证明了新结构的超收敛性质。此外,FVE格式的正交条件和收敛特性之间的关系在表1中进行。数值结果验证了理论分析的正确性。

英文摘要:

New superconvergent structures are introduced by the finite volume element method (FVEM), which allow us to choose the superconvergent points freely. The general orthogonal condition and the modified M-decomposition (MMD) technique are established to prove the superconvergence properties of the new structures. In addition, the relationships between the orthogonal condition and the convergence properties for the FVE schemes are carried out in Table 1. Numerical results are given to illustrate the theoretical results.
