| 英文摘要 | In this work, a recovery technique for the inter-mediate finite element family of the second type is proposed and analysed on a second-order elliptic model problem. It is shown that when the pollution error is properly controlled, the convergence rate of the recovered gradient is two orders higher than the optimal global rate on an interior subdomain where rectangular meshes of regular type are applied. Some numerical results are provided to confirm the theoretical findings. |
