Mass lumping and stabilization for immersogeometric analysis
Yannis Voet, Espen Sande, Annalisa Buffa
Trimmed (multi-patch) geometries are the state-of-the-art technology in computer-aided design for industrial applications such as automobile crashworthiness. In this context, fast…
Fast and Multiscale Formation of Isogeometric matrices of Microstructured Geometric Models
Thibaut Hirschler, Pablo Antolin, Annalisa Buffa
The matrix formation associated to high-order discretizations is known to be numerically demanding. Based on the existing procedure of interpolation and lookup, we design a multisc…
Immersed Boundary-Conformal Isogeometric Method for Linear Elliptic Problems
Xiaodong Wei, Benjamin Marussig, Pablo Antolin +1
We present a novel isogeometric method, namely the Immersed Boundary-Conformal Method (IBCM), that features a layer of discretization conformal to the boundary while employing a si…
A hierarchical approach to the a posteriori error estimation of isogeometric Kirchhoff plates and Kirchhoff-Love shells
Pablo Antolin, Annalisa Buffa, Luca Coradello
This work focuses on the development of a posteriori error estimates for fourth-order, elliptic, partial differential equations. In particular, we propose a novel algorithm to stee…
