Superconvergence of Linear Finite Volume Element Method for Parabolic Problems
摘要
Abstract
As for the linear finite volume element schemes for parabolic problems on triangulation, we proved that the superconvergence property held for the semi-discrete scheme and fully discrete scheme. Furthermore,the superconvergence of numerical gradients at optimal stress points was obtained. Finally numerical example was presented to confirm our theoretical results.关键词
