Isogeometric boundary element analysis using unstructured T-splines

MA Scott, RN Simpson, JA Evans, S Lipton… - Computer Methods in …, 2013 - Elsevier
We couple collocated isogeometric boundary element methods and unstructured analysis-
suitable T-spline surfaces for linear elastostatic problems. We extend the definition of …

Local refinement of analysis-suitable T-splines

MA Scott, X Li, TW Sederberg, TJR Hughes - Computer Methods in Applied …, 2012 - Elsevier
We develop a local refinement algorithm for analysis-suitable T-splines which does not
produce excessive propagation of control points. We then demonstrate its use as an …

Isogeometric finite element data structures based on Bézier extraction of T‐splines

MA Scott, MJ Borden, CV Verhoosel… - International Journal …, 2011 - Wiley Online Library
We develop finite element data structures for T‐splines based on Bézier extraction
generalizing our previous work for NURBS. As in traditional finite element analysis, the …

GeoPDEs: a research tool for isogeometric analysis of PDEs

C De Falco, A Reali, R Vázquez - Advances in Engineering Software, 2011 - Elsevier
GeoPDEs (http://geopdes. sourceforge. net) is a suite of free software tools for applications
on Isogeometric Analysis (IGA). Its main focus is on providing a common framework for the …

Hierarchical T-splines: Analysis-suitability, Bézier extraction, and application as an adaptive basis for isogeometric analysis

EJ Evans, MA Scott, X Li, DC Thomas - Computer Methods in Applied …, 2015 - Elsevier
In this paper hierarchical analysis-suitable T-splines (HASTS) are developed. The resulting
spaces are a superset of both analysis-suitable T-splines and hierarchical B-splines. The …

Isogeometric spline forests

MA Scott, DC Thomas, EJ Evans - Computer Methods in Applied Mechanics …, 2014 - Elsevier
In this paper we present isogeometric spline forests. An isogeometric spline forest is a
hierarchical spline representation capable of representing surfaces or volumes of arbitrarily …

Bézier projection: a unified approach for local projection and quadrature-free refinement and coarsening of NURBS and T-splines with particular application to …

DC Thomas, MA Scott, JA Evans, K Tew… - Computer Methods in …, 2015 - Elsevier
We introduce Bézier projection as an element-based local projection methodology for B-
splines, NURBS, and T-splines. This new approach relies on the concept of Bézier …

Effortless quasi-interpolation in hierarchical spaces

H Speleers, C Manni - Numerische Mathematik, 2016 - Springer
We present a general and simple procedure to construct quasi-interpolants in hierarchical
spaces. Such spaces are composed of a hierarchy of nested spaces and provide a flexible …

Generalized B-splines as a tool in isogeometric analysis

C Manni, F Pelosi, ML Sampoli - Computer Methods in Applied Mechanics …, 2011 - Elsevier
The concept of isogeometric analysis has been proposed in [13], where NURBS are
considered as basis of the analysis, thanks to their ability to construct an exact geometric …
