A a-posteriori error estimate and mesh generation algorithm using boundary node control

초록

In this paper, we propose a simplified pollution adaptive mesh generation algorithm, which concentrate on the boundary node based on the element pollution error indicator. The automatic mesh generation method is followed by either a node-relocation or a node-insertion method. The boundary node relocation phase mildly improves the effectivity index of an error estimator. The node insertion phase greatly improves the error and the factor with the cost of increasing the node numbers.
