Analysis-aware interface coarsening for elliptic problems driven by an equilibrated flux estimator
Denise Grappein, Philipp Weder
We propose an a posteriori error estimator that relies on an equilibrated flux reconstruction to enable analysis-aware interface coarsening decisions in elliptic interface problems…

Adaptive refinement in defeaturing problems via an equilibrated flux a posteriori error estimator
Annalisa Buffa, Denise Grappein, Rafael Vázquez
An adaptive refinement strategy, based on an equilibrated flux a posteriori error estimator, is proposed in the context of defeaturing problems. Defeaturing consists of removing fe…

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…
