Adaptive isogeometric finite element analysis of steady-state groundwater flow
(Journal article; Peer reviewed, 2015)Numerical challenges occur in the simulation of groundwater flow problems because of complex boundary conditions, varying material properties, presence of sources or sinks in the flow domain, or a combination of these. In ... -
Divergence-conforming discretization for Stokes problem on locally refined meshes using LR B-splines
(Journal article; Peer reviewed, 2015)To solve the incompressible flow problems using isogeometric analysis, the div-compatible spline spaces were originally introduced by Buffa et al. (2011), and later developed by Evans (2011). In this paper, we extend the ... -
On the similarities and differences between Classical Hierarchical, Truncated Hierarchical and LR B-splines
(Journal article; Peer reviewed, 2015)Smooth spline functions such as B-splines and NURBS are already an established technology in the field of computer-aided design (CAD) and have in recent years been given a lot of attention from the computer-aided engineering ... -
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 ...
