Isogeometric analysis
The Isogeometric Analysis is an approach for integration of finite element methods (FEM) and NURBS -based CAD methods. In most commercial FEM software packages, after a change to the CAD model, it is necessary to approximate / measure it again in order to be able to simulate it again using FEM. In isogeometric analysis, this step is bypassed and complex NURBS geometries are transferred directly to the finite element application.
The founder of isogeometric analysis is Tom Hughes and his research group at the University of Texas in Austin. There are various software packages that enable the implementation of isogeometric methods, for example FEAP IsoGeometric, GeoPDEs, PetIGA, G + Smo and MIGFEM.
