On the initial higher-order pressure convergence in equal-order finite element discretizations of the Stokes system
(Peer reviewed; Journal article, 2022)In incompressible flow problems, the finite element discretization of pressure and velocity can be done through either stable spaces or stabilized pairs. For equal-order stabilized methods with piecewise linear discretization, ... -
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 ...
