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.
