1. Aspects of adaptive mesh refinement in the spectral element method
Abstract : This thesis deals with the improvement of the efficiency of numerical simulations in computational fluid dynamics. Some of the limitations of current algorithms on future exascale supercomputers are addressed with the main goal of using adaptive mesh refinement for the simulation of turbulent and three-dimensional flows.

2. Towards adaptive mesh refinement in Nek5000
Abstract : The development of adaptive mesh refinement capabilities in the field of computational fluid dynamics is an essential tool for enabling the simulation of larger and more complex physical problems. While such techniques have been known for a long time, most simulations do not make use of them because of the lack of a robust implementation. READ MORE

3. Numerical methods for the Navier–Stokes equations applied to turbulent flow and to multi-phase flow
Abstract : This thesis discusses the numerical approximation of flow problems, in particular the large eddy simulation of turbulent flow and the simulation of laminar immiscible two-phase flow. The computations for both applications are performed with a coupled solution approach of the Navier-Stokes equations discretized with the finite element method. READ MORE

4. Analysis and Implementation of Preconditioners for Prestressed Elasticity Problems : Advances and Enhancements
Abstract : In this work, prestressed elasticity problem as a model of the so-called glacial isostatic adjustment (GIA) process is studied. The model problem is described by a set of partial differential equations (PDE) and discretized with a mixed finite element (FE) formulation. READ MORE
