Introduction to Isogeometric Analysis with LS-DYNA

Isogeometric Analysis (IGA) is a finite element technology in which the geometry description (i.e. shape functions) used in computer-aided design (CAD) is used in the numerical analysis. Besides the potential to better integrate the CAD-models with the subsequent finite element analysis (FEA), the use of higher order shape functions, i.e. non-uniform rational B-splines (NURBS) may yield better results while having the possibility of using larger element sizes. Furthermore, the use of the IGA technology helps reducing the discretization error that may result form the re-parameterization of the CAD design.

This one day class provides an introduction into Isogeometric Analysis (IGA) with Non-Uniform Rational B-Splines (NURBS) in LS-DYNA. Some theoretical background about IGA and NURBS will be presented before exploring the current capabilities in LS-DYNA. Starting from some CAD-file the setup of a suitable model using LS-PREPOST will be exercised. The class will deal with shells and solids with the main focus on shells.
