1. Cut finite element methods on parametric multipatch surfaces
Sammanfattning : .... LÄS MER
2. High Order Cut Finite Element Methods for Wave Equations
Sammanfattning : This thesis considers wave propagation problems solved using finite element methods where a boundary or interface of the domain is not aligned with the computational mesh. Such methods are usually referred to as cut or immersed methods. LÄS MER
3. Numerical Analysis of Evolution Problems in Multiphysics
Sammanfattning : In this thesis we study numerical methods for evolution problems in multiphysics. The term multiphysics is commonly used to describe physical phenomena that involve several interacting models. Typically, such problems result in coupled systems of partial differential equations.

4. Cut isogeometric methods on trimmed multipatch surfaces
Sammanfattning : Partial differential equations (PDE) on surfaces appear in a variety of applications, such as image processing, modeling of lubrication, fluid flows, diffusion, and transport of surfactants. In some applications, surfaces are drawn and modeled by using CAD software, giving a very precise patchwise parametric description of the surface. LÄS MER
5. Cut finite element methods for interface problems
Sammanfattning : Interface problems modeled by Partial Differential Equations (PDEs) appear in a wide range of fields such as biology, fluid dynamics, micro and nano-technologies. In computer simulations of such problems a fundamental task is to numerically solve PDEs in/on domains defined by deformable interfaces/geometries. LÄS MER
