Uniting the workflows of geometric design and numerical analysis is one of the challenging aims of IsoGeometric Analysis. Such a goal is addressed by using the same mathematical functions — namely, Non-Uniform Rational B-Splines — to describe the

In this work, we explore the usefulness of spaces of unstructured spline functions in the resolution of hyperbolic problems discretized by explicit-time schemes, and especially the acoustic wave propagation problem with absorbing boundary conditions,

Time-dependent domains are encountered in a vast category of fluid mechanics applications. Such problems are often characterised by complex geometries and physical phenomena. The aim of the present dissertation is the development of an accurate and r

The present work develops a highly efficient computational approach so-called semi-analytical isogeometric Galerkin (SAIGA-G) and semi analytical isogeometric collocation (SAIGA-C) to compute the wave dispersion in different types of waveguide posses

In this work, we introduce different weak formulations based on time continuous Galerkin methods for several types of problems, governed by partial differential equations in space and time. Our approach is based on a simultaneous and arbitrary discre

The concept of isogeometric analysis generalizes the finite element method by the use of spline functions richer than the traditional Lagrange functions which impose an approximation of the considered geometry. Its main motivation is to link design w
