LS-DYNA Compact: 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 also 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 and higher-continuity shape functions, e.g. 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 from a re-parameterization of the CAD geometry.

This webinar is divided into two parts:

Part I - Introduction to Isogeometric Analysis in LS-DYNA

  • General introduction to Isogeometric Analysis
  • Theoretical basics of B-Splines, NURBS (Non-Uniform Rational B-Splines) and refinement strategies
  • Theoretical background of analysis with NURBS
  • Isogeometric Analysis in LS-DYNA and LS-PrePost
  • LS-PrePost tutorial for simple shell and solid models

Part II – Advanced IGA for Industrial Applications

  • Industrial B-Rep CAD models
  • The new CAD-inspired *IGA keyword format
  • IGA on industrial shell models: analysis capabilities and examples
  • ANSA tutorial for industrial shell models
  • Outlook to solids and novel spline technologies

Each Session is scheduled from 9 to 11 am (CET) on two consecutive days.
