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…

A Certified Goal-Oriented A Posteriori Defeaturing Error Estimator for Elliptic PDEs
Philipp Weder, Annalisa Buffa
Defeaturing, the process of simplifying computational geometries, is a critical step in industrial simulation pipelines for reducing computational cost. Rigorous a posteriori estim…

Analysis-Aware Defeaturing of Dirichlet Features
Philipp Weder, Annalisa Buffa
Feature removal from computational geometries, or defeaturing, is an integral part of industrial simulation pipelines. Defeaturing simplifies the otherwise costly or even impossibl…
