A Reduced Basis Method for steady Stokes flow
Snekkerhaugen, Lars (Master thesis, 2018)In light of the increasing demand for many-query and real-time PDE solutions, reduced basis methods stand as a promising technique for developing solvers with the desired performance. In this thesis, we present the theory ... -
An adaptive isogeometric finite element analysis
Johannessen, Kjetil André (Master thesis, 2009)In this thesis we will explore the possibilities of making a finite element solver for partial differential equations using the isogeometric framework established by Hughes et al. Whereas general B-splines and NURBS only ... -
Isogeometric Analysis Using Locally Refined B-splines
Johannessen, Kjetil André (Doctoral thesis at NTNU;2014:376, Doctoral thesis, 2014) -
Isogeometric Finite Element Analysis using B-spline Basis Functions: The Poisson Equation and the Biharmonic Equation
Solberg, Turid Schoonderbeek (Master thesis, 2013)In this thesis the finite element method with B-spline basis functions was implemented and tested for the Poisson equation and the Biharmonic equation in an isoparametric setting. The equations were solved on a unit square ... -
Mesh Generation Techniques for Isogeometric Analysis
Mothes Hansvold, Kine Aurora (Master thesis, 2015)In any method aimed at solving a boundary value problem using isogeometric analysis, it is imperative to find a high quality parameterization of the domain over which the partial differential equation is posed. The ... -
Simulation of crack propagation using isogeometric analysis applied with NURBS and LR B-splines
Nilsen, Oda Kulleseid (Master thesis, 2012)This report features the isogeometric finite element method applied to the elastodynamic problem in a brittle medium with a potential for cracking. Griffith's theory for fracturing is used. The development of the model is ...
