An interior penalty coupling strategy for isogeometric non-conformal Kirchhoff-Love shell patches
Annalisa Buffa, Pablo Antolin Sanchez, Giuliano Guarino
This work focuses on the coupling of trimmed shell patches using Isogeometric Analysis, based on higher continuity splines that seamlessly meet the C 1 \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackag ...
Springer2024Region Extraction in Mesh Intersection
Annalisa Buffa, Pablo Antolin Sanchez, Emiliano Cirillo
Region extraction is a very common task in both Computer Science and Engineering with several applications in object recognition and motion analysis, among others. Most of the literature focuses on regions delimited by straight lines, often in the special ...
2023DeepBND: A machine learning approach to enhance multiscale solid mechanics
Annalisa Buffa, Simone Deparis, Pablo Antolin Sanchez, Felipe Figueredo Rocha
Effective properties of materials with random heterogeneous structures are typically determined by homogenising the mechanical quantity of interest in a window of observation. The entire problem setting encompasses the solution of a local PDE and some aver ...
2023Fast parametric analysis of trimmed multi-patch isogeometric Kirchhoff-Love shells using a local reduced basis method
Annalisa Buffa, Pablo Antolin Sanchez, Margarita Chasapi
This contribution presents a model order reduction framework for real-time efficient solution of trimmed, multi-patch isogeometric Kirchhoff-Love shells. In several scenarios, such as design and shape optimization, multiple simulations need to be performed ...
2023Analysis-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 ...
Hoboken2023Quadrature-free immersed isogeometric analysis
Pablo Antolin Sanchez, Thibaut Hirschler
This paper presents a novel method for solving partial differential equations on three-dimensional CAD geometries by means of immersed isogeometric discretizations that do not require quadrature schemes. It relies on a newly developed technique for the eva ...
SPRINGER2022Robust numerical integration on curved polyhedra based on folded decompositions
Annalisa Buffa, Pablo Antolin Sanchez, Xiaodong Wei
We present a novel method to perform numerical integration over curved polyhedra enclosed by high-order parametric surfaces. Such a polyhedron is first decomposed into a set of triangular and/or rectangular pyramids, whose certain faces correspond to the g ...
ELSEVIER SCIENCE SA2022Reduced order modelling of nonaffine problems on parameterized NURBS multipatch geometries
Annalisa Buffa, Pablo Antolin Sanchez, Margarita Chasapi
This contribution explores the combined capabilities of reduced basis methods and IsoGeometric Analysis (IGA) in the context of parameterized partial differential equations. The introduction of IGA enables a unified simulation framework based on a single g ...
2022A localized reduced basis approach for unfitted domain methods on parameterized geometries
Annalisa Buffa, Pablo Antolin Sanchez, Margarita Chasapi
This work introduces a reduced order modeling (ROM) framework for the solution of parameterized second-order linear elliptic partial differential equations formulated on unfitted geometries. The goal is to construct efficient projection-based ROMs, which r ...
