An equilibrated flux a posteriori error estimator for defeaturing problems
Annalisa Buffa, Ondine Chanon, Denise Grappein +2
An a posteriori error estimator based on an equilibrated flux reconstruction is proposed for defeaturing problems in the context of finite element discretizations. Defeaturing cons…

Inexpensive polynomial-degree-robust equilibrated flux a posteriori estimates for isogeometric analysis
Gregor Gantner, Martin Vohralík
We consider isogeometric discretizations of the Poisson model problem, focusing on high polynomial degrees and strong hierarchical refinements. We derive a posteriori error estimat…
