16. Procedures in Adaptive Finite Element Analysis
Abstract : The present work is concerned with topics related to some adaptive methods for the approximate solution of differential equations. Emphasis is on the finite element method for second order elliptic equations, where we use either p-refinement or remeshing with an advancing front mesh generator in order to improve approximate solutions.

17. Adaptive finite element methods for multiphysics problems
Abstract : In this thesis we develop and analyze the performance ofadaptive finite element methods for multiphysics problems. Inparticular, we propose a methodology for deriving computable errorestimates when solving unidirectionally coupled multiphysics problemsusing segregated finite element solvers. READ MORE

18. Adaptive Finite Element Methods for Div-Curl Problems
Abstract : In this thesis, we develop and apply finite element methods to problems of div-curl type, mainly from applications in electromagnetics. In particular, we focus on least-squares formulations for problems with singularities, edge elements in eddy current computations, and the implementation of the finite element method. READ MORE

19. High performance adaptive finite element methods for turbulent fluid flow
Abstract : Understanding the mechanics of turbulent fluid flow is of key importance for industry and society as for example in aerodynamics and aero-acoustics. The massive computational cost for resolving all turbulent scales in a realistic problem makes direct numerical simulation of the underlying Navier-Stokes equations impossible. READ MORE

20. Linear and Non-Linear Analysis of Plates and Shells by Use of Morley Finite Elements
Abstract : The thesis deals with plate bending analysis and shell analysis in static linear and dynamic non-linear situations. The thesis contains two parts. In common for them is the use of the Germain-Kirchhoff plate theory, constant strain, constant curvature triangular plate elements and adaptive improvement of original solution. READ MORE
