One of the major problems in product design is the gap between CAD, where the geometrical shape of the object is defined, and CAE, where the mechanical behavior of the shape is analysed. The gap results from different representations used for design (based on NURBS) and analysis (based on a finite: The design, encapsulated in a CAD model, is approximated by a finite element mesh (FEM) for analysis. Isogeometric Analysis refers to the extension of the standard FEM to representations used in CAGD. By working directly with the CAD model, isogeometric analysis effectively eliminates the problems associated with generating a finite element mesh from a CAD model.
