  4. 2. Adaptive Solvers for High-Dimensional PDE Problems on Clusters of Multicore Processors

    Author : Magnus Grandin; Sverker Holmgren; Michael Thuné; Michael Bader; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; adaptive mesh refinement; anisotropic refinement; exponential integrators; Lanczos algorithm; hybrid parallelization; time-dependent Schrödinger equation; Scientific Computing; Beräkningsvetenskap;

    Abstract : 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. READ MORE

  5. 3. Contributions to the Modeling and Simulation of Mechanical Systems with Detailed Contact Analyses

  6. 4. High Performance Adaptive Finite Element Methods : With Applications in Aerodynamics

    Author : Niclas Jansson; Johan Hoffman; Johan Jansson; Vincent Heuveline; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The massive computational cost for resolving all scales in a turbulent flow makes a direct numerical simulation of the underlying Navier-Stokes equations impossible in most engineering applications. Recent advances in adaptive finite element methods offer a new powerful tool in Computational Fluid Dynamics (CFD). READ MORE

  7. 5. Implementation of complex polarization propagator theory for linear response properties of large molecular systems

    Author : Manuel Brand; Patrick Norman; Berta Fernández Rodríguez; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical Chemistry and Biology; Teoretisk kemi och biologi;

    Abstract : Since its beginning, the remarkable development from the first commercially available computers toward exascale supercomputers just within the span of a lifetime has been closely intertwined with the perpetual quest for the utilization of the arising computing power for the avail of theoretical chemistry. With the aim of further pushing the limits of computationally accessible molecular system sizes, this thesis includes the presentation of programming efforts, which brought forth two quantum chemical software codes, as well as a range of ab initio studies on carbon-based systems, enabled by the former.
