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 …

Most modeling approaches lie in either of the two categories: physics‐based or data‐driven.
Recently, a third approach which is a combination of these deterministic and statistical …

In this article, we address adaptive methods for isogeometric analysis based on local
refinement guided by recovery based a posteriori error estimates. Isogeometric analysis was …

In this paper a new stress recovery procedure is presented. The formulation is very simple
and based on improving stresses by enforcing compatibility over local patches of elements …

Numerical challenges occur in the simulation of groundwater flow problems because of
complex boundary conditions, varying material properties, presence of sources or sinks in …

In this article, we present an efficient recovery-based a posteriori error estimator for adaptive
isogeometric analysis (IGA) of the Stokes equation, which is straightforward to implement …

Within the framework of the displacement‐based virtual element method (VEM), namely, for
plane elasticity, an important topic is the development of optimal techniques for the …

The present work deals with an a posteriori error estimator for linear finite element analysis,
based on a stress recovery procedure called Recovery by Compatibility in Patches. The key …

In this paper a study is performed on application of two recovery methods, ie
superconvergent patch recovery (SPR) and the recovery by equilibrium of patches (REP), to …

A new patch based stress recovery procedure for elastoplastic analysis is presented in this
paper. The formulation derives from the extension to the elastic-perfectly plastic case of the …
