1. Filtering aspects
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : In this report, a Fourier spectral approximation of the solution to the linear convection--diffusion equation for initial conditions of different smoothness, and for Burger's equation for the initial condition f(x) = sin(x), was constructed, and implemented. Three different filters (Cesàro, Lanczos, and 4--th order exponential cutoff) were either applied to the initial condition or to the numerical approximation after the last integration step has been performed.

2. Solving Korteweg-de Vries equations with Discontinuous Galerkin methods
Master-uppsats, Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakultetenSammanfattning : In this thesis the Discontinuous Galerkin approximation performance applied to the Korteweg–de Vries equation is investigated. This equation is nonlinear with a third spatial derivative and can be used for shallow water movement. LÄS MER
3. Comparative Analysis of Adaptive Domain Decomposition Algorithms for a Time-Spectral Method
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Time-spectral solvers for partial differential equations (PDE) have been explored in various forms during the last few decades. The generalized weighted residual method (GWRM) is one such method with a high accuracy and efficiency. The GWRM has so far been implemented almost exclusively with a uniform grid of subdomains in the spatial domain. LÄS MER
4. Simulation of Viscosity-Stratified Flow
Kandidat-uppsats,Sammanfattning : The aim of this project is to study the viscous Burgers' equation for the case where the viscosity is constant, but also when it contains a jump in viscosity. In the first case where the viscosity is constant, Burgers' is simply solved on a singular domain. LÄS MER
5. A stable and accurate hybrid FE-FD method
Master-uppsats, Uppsala universitet/Institutionen för informationsteknologiSammanfattning : We develop a hybrid method to couple finite difference methods and finite element methods in a nonconforming multiblock fashion. The aim is to optimize computational efficiency when complex geometries present. LÄS MER
