Journal ArticleDOI
An Isogeometric design-through-analysis methodology based on adaptive hierarchical refinement of NURBS, immersed boundary methods, and T-spline CAD surfaces
Dominik Schillinger,Dominik Schillinger,Luca Dedè,Michael A. Scott,John A. Evans,Michael J. Borden,Ernst Rank,Thomas J. R. Hughes +7 more
TL;DR: It is shown that hierarchical refinement considerably increases the flexibility of this approach by adaptively resolving local features of NURBS, which combines full analysis suitability of the basis with straightforward implementation in tree data structures and simple generalization to higher dimensions.
Journal ArticleDOI
An immersogeometric variational framework for fluid-structure interaction: Application to bioprosthetic heart valves
David Kamensky,Ming-Chen Hsu,Dominik Schillinger,John A. Evans,Ankush Aggarwal,Yuri Bazilevs,Michael S. Sacks,Thomas J. R. Hughes +7 more
TL;DR: This paper develops a geometrically flexible technique for computational fluid-structure interaction (FSI) that directly analyzes a spline-based surface representation of the structure by immersing it into a non-boundary-fitted discretization of the surrounding fluid domain, and introduces the term "immersogeometric analysis" to identify this paradigm.
Journal ArticleDOI
The Finite Cell Method: A Review in the Context of Higher-Order Structural Analysis of CAD and Image-Based Geometric Models
Dominik Schillinger,Martin Ruess +1 more
TL;DR: This review article provides a concise introduction to the basics of the finite cell method, and summarizes recent developments of the technology, with particular emphasis on the research topics in which the author has been actively involved.
Journal ArticleDOI
Isogeometric collocation: Cost comparison with Galerkin methods and extension to adaptive hierarchical NURBS discretizations
TL;DR: An adaptive isogeometric collocation method is explored that is based on local hierarchical refinement of NURBS basis functions and collocation points derived from the corresponding multi-level Greville abscissae, and introduces the concept of weighted collocation that can be consistently developed from the weighted residual form and the two-scale relation of B-splines.
Journal ArticleDOI
Weak coupling for isogeometric analysis of non-matching and trimmed multi-patch geometries
TL;DR: It is shown that the combination of weak coupling with the finite cell method opens the door for a truly isogeometric treatment of trimmed B-spline and NURBS geometries that eliminates the need for costly reparameterization procedures.
