 Isogeometric analysis

Isogeometric Analysis (IGA) is a numerical method that integrates finite element analysis (FEA) and computer-aided design (CAD) within a unified framework. It utilizes the same basis functions used for geometric representation in CAD, such as Non-Uniform Rational B-Splines (NURBS), to represent both the geometry of the computational domain and the solution of partial differential equations (PDEs) over that domain.
