WitrynaIn order to eliminate the negative influence of the FEM on TO, IsoGeometric Analysis (IGA) has become a promising alternative due to its unique feature that the Computer-Aided Design (CAD) model and Computer-Aided Engineering (CAE) model can be unified into a same mathematical model. Witryna1 lis 2009 · In isogeometric analysis the functions from the geometry description are used as basis functions for the analysis. Thus, the analysis works on a geometrically exact model and no meshing is necessary. This offers a possibility to close the existing gap between design and analysis as both use the same geometry model.
