The concept of Isogeometric Analysis (IGA) was introduced by Hughes with the aim of bridging the gap between computer aided design (CAD) and the finite element method. This aim is pursued by adopting the same Non Uniform Rational BSpline (NURBS) basis functions to construct both trial and test spaces in the discrete variational formulation of differential problems as are used to design domain geometries in CAD applications. As an additional benefit with respect to standard finite elements, the use of NURBS functions allows to construct finite dimensional spaces of higher regularity. In this talk we discuss the general concepts of IGA and show some interesting applications to simulations arising from different fields of physics, including incompressible fluid dynamics, electromagnetics (in particular: accelerator cavities), quantum mechanics and linear elasticity.
This talk is provided together with the department of electrical engineering and information technology.
