Isogeometric Analysis (IGA) was originally developed by T.J.R. Hughes and co-workers in order to unify Computer Aided Engineering (CAE) and Computer Aided Design (CAD). This is accomplished by incorporating CAD basis functions in numerical analysis. Most commonly, NURBS were used in IGA though recently other CAD-newcomers have been exploited such as T-splines, subdivision surfaces, LR-splines, polycube splines or PHT-splines. Recent efforts to develop standardized file formations used in both CAD and CAE have enabled the solution of complex physical phenomena involving complex geometries. It was shown that IGA has advantages over classical finite element analysis based on Lagrange polynomials for several applications including large deformations, contact or plasticity. Other aspects of IGA concern mesh generation, the development of novel elements, studies on robustness, integration, to name a few.

Though IGA is a significant improvement, many challenges remain in this newly evolving discipline. Standardized mesh generation for complex three-dimensional volume meshes, automated surface parametrization or the application to complex multi-physics or multiscale analysis still require further developments.

The purpose of this mini-symposium is aimed in reporting recent developments and contributions in IGA. It should bring together experts from Computational Geometry and Computational Mechanics.
