1. Numerical Simulation of the Generalized Modified Benjamin-Bona-Mahony Equation Using SBP-SAT in Time
Kandidat-uppsats, Uppsala universitet/Avdelningen för beräkningsvetenskapSammanfattning : This paper describes simulations of the generalized modified Benjamin-Bona-Mahony (BBM) equation, using finite difference methods (FDM). Well-posed boundary conditions (BCs) as well as stable semi-discrete approximations are derived using summations-by-parts (SBP) operators combined with the projection method. LÄS MER
2. An exploration of classical SBP-SAT operators and their minimal size
Kandidat-uppsats, Linnéuniversitetet/Institutionen för matematik (MA)Sammanfattning : We consider diagonal-norm classical summation-by-parts (SBP) operators us-ing the simultaneous approximation term (SAT) method of imposing boundaryconditions. We derive a formula for the inverse of these SBP-SAT discretizationmatrices. LÄS MER
3. Numerical Simulation of Soliton Tunneling
Kandidat-uppsats,Sammanfattning : This project studied two different ways of imposing boundary conditions weakly with the finite difference summation-by-parts (SBP) operators. These operators were combined with the boundary handling methods of simultaneous-approximation-terms (SAT) and the Projection to impose homogeneous Neumann and Dirichlet boundary conditions. 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. Estimation of Hourly Origin Destination Trip Matrices for a Model of Norrköping
Master-uppsats, Linköpings universitet/Kommunikations- och transportsystem; Linköpings universitet/Tekniska fakultetenSammanfattning : During the last century, the number of car users has increased as an effect of the increasing population growth. To manage the environmental and infrastructural challenges that comes with a more congested traffic network, traffic planning has become of higher importance to analyze the current traffic state and to predict future capacity challenges and effects of investments.
