  1. 1. Summation-by-Parts Operators for High Order Finite Difference Methods

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Ken Mattsson; Jan Nordström; Gunilla Kreiss; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; finite difference methods; accuracy; stability; dissipation; Numerical Analysis; Numerisk analys;

    Abstract : High order accurate finite difference methods for hyperbolic and parabolic initial boundary value problems (IBVPs) are considered. Particular focus is on time dependent wave propagating problems in complex domains. Typical applications are acoustic and electromagnetic wave propagation and fluid dynamics. READ MORE

  3. 3. Hybrid Methods for Unsteady Fluid Flow Problems in Complex Geometries

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jing Gong; Uppsala universitet.; Uppsala universitet.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hybrid methods; finite difference methods; finite volume methods; coupling procedure; stability; efficiency; artificial dissipation; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Abstract : In this thesis, stable and efficient hybrid methods which combine high order finite difference methods and unstructured finite volume methods for time-dependent initial boundary value problems have been developed. The hybrid methods make it possible to combine the efficiency of the finite difference method and the flexibility of the finite volume method. READ MORE
