Isogeometric analysis is one of the most important trends in numerical analysis in the last decade.

It seeks to integrate the CAD design process with the FEA analysis process. Game-changing advantages of this approach are twofold.

First, the reuse of the geometry description in analysis avoids time consuming geometry clean-up and mesh generation steps at every design iteration. Secondly, the resulting discretization turns out to have favorable approximation properties compared to traditional FEA discretizations
