IGA for Industrial Applications

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.
