Isogeometric homogenization of unidirectional nanocomposites with energetic surfaces [PDF]
The present work aims to propose an interface-enriched isogeometric analysis strategy for predicting the size-dependent effective moduli and local stress field of periodic arrays of nanosize inhomogeneity.

Generating Star-Shaped Blocks for Scaled Boundary Multipatch IGA
, 2022 S.1-25This paper deals with the decomposition of a domain into star-shaped blocks, which is motivated by the idea of solving PDEs by means of the scaled boundary isogeometric analysis (SB-IGA). In the first part of the paper an introduction to the SB-IGA

Volume Quantization with Flexible Singularities for Hexahedral Meshing
Computer Graphics Forum, EarlyView.Abstract We present a novel algorithm for quantization and subsequent hexahedral mesh generation from seamless volumetric maps. Quantization is the process of choosing integers that represent the numbers of hexahedral elements to be placed in each region of the volume, and transforming the seamless map into an integer‐grid map matching that choice ...

Planar Parametrization in Isogeometric Analysis [PDF]
, 2014 Before isogeometric analysis can be applied to solving a partial differential equation posed over some physical domain, one needs to construct a valid parametrization of the geometry. The accuracy of the analysis is affected by the quality of the parametrization.

DiskScissors: Cutting Arbitrary‐Topology Solids for Bijective Mapping
Computer Graphics Forum, EarlyView.Abstract An algorithm for cutting solid objects in a topology‐controlled manner is presented. Concretely, given a loop on the object boundary, a disk‐topology cut surface bounded by the loop is constructed in the interior. In contrast to various previous approaches, both disk topology and conformance to the prescribed loop are ensured by construction ...
