IGA 1: Why Isogeometric Analysis ?

Here I am trying to present an intuitive understanding about the need, importance and purpose of Isogeometric Analysis (IGA), which was developed in 2005 as an alternate/extension of classical FEM.

Isogeometric Analysis of Multi-patch Geometry

Isogeometric analysis (IGA) aims at bridging the gap between Computer Aided Design (CAD) and Computer Aided Engineering (CAE) by utilizing Non-uniform rational B-splines (NURBS), which is used for geometric description, as the basis for approximating the solution in CAE environment. However, IGA is not always straightforward, like in case of complex geometries which are generally […]
