Machine learning discovery of optimal quadrature rules for isogeometric analysis

T Teijeiro, JM Taylor, A Hashemian, D Pardo - Computer Methods in …, 2023‏ - Elsevier
We propose the use of machine learning techniques to find optimal quadrature rules for the
construction of stiffness and mass matrices in isogeometric analysis (IGA). We initially …

Goal-adaptive meshing of isogeometric Kirchhoff–Love shells

HM Verhelst, A Mantzaflaris, M Möller… - Engineering with …, 2024‏ - Springer
Mesh adaptivity is a technique to provide detail in numerical solutions without the need to
refine the mesh over the whole domain. Mesh adaptivity in isogeometric analysis can be …

[HTML][HTML] Fast immersed boundary method based on weighted quadrature

B Marussig, R Hiemstra, D Schillinger - Computer Methods in Applied …, 2023‏ - Elsevier
Combining sum factorization, weighted quadrature, and row-based assembly enables

Fast formation and assembly for spline‐based 3D fictitious domain methods

B Marussig - PAMM, 2023‏ - Wiley Online Library
Standard finite element methods employ an element‐wise assembly strategy. The element's
contribution to the system matrix is formed by a loop over quadrature points. This concept is …
