我们研究的方法恢复张量度量从给定的误差估计和性质的网格是准均匀的,在这些度量。我们推导出这些网格上的全局误差的最优上界和下界。我们用数值实验证明,基于边缘的误差估计比传统的基于元素的误差估计更适合于恢复各向异性度量。
We study methods for recovering tensor metrics from given error estimates and properties of meshes which are quasi-uniform in these metrics. We derive optimal upper and lower bounds for the global error on these meshes. We demonstrate with numerical experiments that the edge-based error estimates are preferable for recovering anisotropic metrics than the conventional element-based errors estimates.
