An equilibrated flux a posteriori error estimator for defeaturing problems
Annalisa Buffa, Denise Grappein, Rafael Vazquez Hernandez, Ondine Gabrielle Chanon
An a posteriori error estimator based on an equilibrated flux reconstruction is proposed for defeaturing problems in the context of finite element discretizations. Defeaturing consists in the simplification of a geometry by removing features that are consi ...
2023A Shape Derivative Approach to Domain Simplification
Annalisa Buffa, Jochen Peter Hinz, Ondine Gabrielle Chanon, Alessandra Arrigoni
The objective of this study is to address the difficulty of simplifying the geometric model in which a differential problem is formulated, also called defeaturing, while simultaneously ensuring that the accuracy of the solution is maintained under control. ...
Oxford2023Analysis-aware defeaturing of complex geometries with Neumann features
Pablo Antolin Sanchez, Ondine Gabrielle Chanon
Local modifications of a computational domain are often performed in order to simplify the meshing process and to reduce computational costs and memory requirements. However, removing geometrical features of a domain often introduces a non-negligible error ...

2022An a posteriori error estimator for isogeometric analysis on trimmed geometries
Annalisa Buffa, Rafael Vazquez Hernandez, Ondine Gabrielle Chanon
Trimming consists of cutting away parts of a geometric domain, without reconstructing a global parametrization (meshing). It is a widely used operation in computer-aided design, which generates meshes that are unfitted with the described physical object. T ...
2022Data-Driven Unknown-Input Observers and State Estimation
Giancarlo Ferrari Trecate, Mustafa Sahin Turan
Unknown-input observers (UIOs) allow for estimation of the states of an LTI system without knowledge of all inputs. In this letter, we provide a novel data-driven UIO based on behavioral system theory and the result known as Fundamental Lemma proposed by J ...
2022Probabilistic and Bayesian methods for uncertainty quantification of deterministic and stochastic differential equations
In this thesis we explore uncertainty quantification of forward and inverse problems involving differential equations. Differential equations are widely employed for modeling natural and social phenomena, with applications in engineering, chemistry, meteor ...
EPFL2021MATHICSE Technical Report : Analysis-aware defeaturing: problem setting and a posteriori estimation
Annalisa Buffa, Rafael Vazquez Hernandez, Ondine Gabrielle Chanon
Defeaturing consists in simplifying geometrical models by removing the geometrical features that are considered not relevant for a given simulation. Feature removal and simplification of computer-aided design models enables faster simulations for engineeri ...
