1. Adaptive Geometric Numerical Integration of Mechanical Systems
Sammanfattning : This thesis is about structure preserving numerical integration of initial value problems, i.e., so called geometric numerical integrators. LÄS MER
2. Computational Stability and Adaptive Strategies - An Experimental Study of ODE Software
Sammanfattning : The algorithmic content of adaptive ODE/DAE software is dominated by a considerable amount of control structures, support algorithms and logic. The control logic has been largely heuristic and lacking support by analysis. LÄS MER
3. Adaptive Finite Element Procedures in Structural Dynamics
Sammanfattning : This thesis deals with a posteriori error estimation and adaptivity in finite element procedures for the analysis of structural dynamic problems. First, error estimation and adaptivity for the Newmark time integration method are studied. LÄS MER
4. On adaptive finite element procedures for static and dynamic problems
Sammanfattning : .... LÄS MER
5. Adaptive Solvers for High-Dimensional PDE Problems on Clusters of Multicore Processors
Sammanfattning : Accurate numerical solution of time-dependent, high-dimensional partial differential equations (PDEs) usually requires efficient numerical techniques and massive-scale parallel computing. In this thesis, we implement and evaluate discretization schemes suited for PDEs of higher dimensionality, focusing on high order of accuracy and low computational cost. LÄS MER
