Further fundamental topics of research within IGA include the analysis of trimmed NURBS, as well as the development, analysis, and testing of flexible local refinement technologies based, e.g., on T-Splines, hierarchical B-Splines, or locally-refined splines, in the framework of unstructured multipatch parameterizations. ![]() Nowadays, a well-established mathematical theory and successful applications to solid, fluid, and multiphysics problems render NURBS functions a genuine analysis technology, paving the way for the application of IGA to solve a number of problems of academic and industrial interest. ![]() Non-Uniform Rational B-Splines (NURBS) were used as a first basis function technology within IGA. However, in the course of IGA development, it was found that isogeometric methods not only improve the geometry modeling within analysis, but also appear to be preferable to standard finite elements in many applications on the basis of per-degree-of-freedom accuracy. in 2005, to generalize and improve finite element analysis in the area of geometry modeling and representation. Isogeometric Analysis (IGA) has in fact been originally introduced and developed by Tom Hughes et al. ![]()
