A framework of shape optimisation based on the isogeometric BEM
This is an implementation of shape optimisation solver based on the isogeometric boundary element method (IGBEM). The details are described in a paper "A framework of shape optimisation based on the isogeometric boundary element method toward designing thin-silicon phtovoltaic devices" submitted to the journal "Engieering with Computers".
Non-Uniform Rational Lagrange (NURL) function toolbox
This package includes a collection of routines for the creation and operation of Non-Uniform Rational Lagrange (NURL) function geometries and its applications to isogeometric analysis of in-plane and flexural vibration of thin plates, based on the NURL toolbox by Bo Liu. The package includes 3 sub-packages: (1) a basic NURL package for the creation and operation of NURL geometries and isogeometric analysis. (2) A NURL curve package. This package includes routines for creation and operation...
A package for Isogeometric Analysis in Octave and Matlab
GeoPDEs is a suite of software tools for research on Isogeometric Analysis of PDEs. GeoPDEs is free software implemented in Octave and fully compatible with Matlab. GeoPDEs is no longer developed at SF, and has moved to GitHub. Please visit http://rafavzqz.github.io/geopdes/ The mailing list will remain active. Releases up to 2.0.4 can be found here. From version 2.1.0 onward, see https://github.com/rafavzqz/geopdes
Open source 3D Matlab Isogeometric Analysis Code
Isogeometric analysis (IGA) is a fundamental step forward in computational mechanics that offers the possibility of integrating methods for analysis into Computer Aided Design (CAD) tools and vice versa. The benefits of such an approach are evident, since the time taken from design to analysis is greatly reduced leading to large savings in cost and time for industry. The tight coupling of CAD and analysis within IGA requires knowledge from both fields and it is one of the goals of the MIGFEM...
NURBS-based elastic and limit analysis of masonry arches in MATLAB
ArchNURBS is a MATLAB tool for the analysis of planar curved structures, with a particular attention to masonry arches. As in CAD softwares, the geometry of the model is defined by a NURBS representation of the structure. Indeed, the user can upload geometries imported from a CAD environment. Based on such a representation, ArchNURBS performs the elastic isogeometric finite element analysis and the collapse limit analysis of the structure. It is possible to include in the analysis the presence...
Matlab code for conducting isogeometric analysis using NURBS
This matlab code presents an introduction to isogeometric analysis whereby the basis functions that are used for computer aided geometric design (CAGD) are also used for approximation in finite element analysis. The present code uses Non-Uniform Rational B-Splines but it should be noted that the CAGD community is making headway towards other descriptions of the geometry, overcoming the limitations of NURBS such as lack of water-tightness. The code also illustrates enrichment through...
Isogeometric boundary element analysis with matlab
This code holds all the matlab files necessary to run a 2D isogeometric code for elastostatic analysis. For more guidance, it is probably a good idea to have a look through the code repository, and more recent updates to the code may also be present here. The main idea is that instead of using conventional Lagrangian polynomials to discretise the unknown fields and geometry (using the isoparametric concept), the basis functions that are used in Computer Aided Design (CAD) are used instead...
