Isogeometric Analysis of Aneurysm Enlargement in Thick-Walled Arteries

Isogeometric Analysis (IGA) is an emerging technology with the potential to revolutionize the finite element method. Here we
present the basics of IGA using NURBS. In particular, we will highlight a few development in making a smooth transition from traditional FEM to IGA. By changing only the shape function routines, a traditional FEM code can be used to perform IGA. We will also present several applications of IGA to computational problems: crack propagation, drug therapy for vulnerable placques, fluid-structure interaction in aortic blood flow simulations, and enlargement of
cranial aneurysms. We will see that IGA works well in these
simulations.
