Simple a posteriori error estimators in adaptive isogeometric analysis
(Journal article; Peer reviewed, 2015)n this article we propose two simple a posteriori error estimators for solving second order elliptic problems using adaptive isogeometric analysis. The idea is based on a Serendipity1pairing of discrete approximation spaces ... -
Superconvergent patch recovery and a posteriori error estimation technique in adaptive isogeometric analysis
(Journal article; Peer reviewed, 2016)Highlights • A posteriori error estimation methodology for adaptive isogeometric analysis using LR B-splines is developed. • Superconvergent patch recovery of gradient field on adaptive meshes is developed. • Algorithm for ...
