21. An adaptive finite element method for the compressible Euler equations
Sammanfattning : This work develops a stabilized finite element method for the compressible Euler equations and proves an a posteriori error estimate for the approximated solution. The equations are approximated by the cG(1)cG(1) finite element method with continuous piecewise linear functions in space and time. LÄS MER
22. Adaptivity for Stochastic and Partial Differential Equations with Applications to Phase Transformations
Sammanfattning : his work is concentrated on efforts to efficiently compute properties of systems, modelled by differential equations, involving multiple scales. Goal oriented adaptivity is the common approach to all the treated problems. LÄS MER
23. Efficient and Reliable Simulation of Quantum Molecular Dynamics
Sammanfattning : The time-dependent Schrödinger equation (TDSE) models the quantum nature of molecular processes. Numerical simulations based on the TDSE help in understanding and predicting the outcome of chemical reactions. LÄS MER
24. Computational modeling of complex flow : Doctoral thesis at Chalmers University of Technology
Sammanfattning : In this thesis we consider the following aspects of computational modeling of complex flows: (i) subgrid modeling, (ii) stability, (iii) a posteriori error estimation, and (iv) computational platform. We develop a framework for adaptivity and error control for multiscale problems, in particular for turbulent flow, based on a posteriori error estimates. LÄS MER
25. Numerical methods for quantum molecular dynamics
Sammanfattning : The time-dependent Schrödinger equation models the quantum nature of molecular processes. Numerical simulations of these models help in understanding and predicting the outcome of chemical reactions. LÄS MER
