Polynomial preserving recovery on boundary

[摘要] In this paper, we propose two systematic strategies to recover the gradient on the boundary of a domain. The recovered gradient has comparable superconvergent property on the boundary as that in the interior of the domain. This superconvergence property has been validated by several numerical experiments. (C) 2016 Elsevier B.V. All rights reserved.
