  1. 16. Multiblock Implementation of PML for the Wave Equation

    University essay from Institutionen för informationsteknologi

    Author : Khairi Arafeh; [2010]
    Keywords : ;

    Abstract : The implementation of PML for the wave equation is considered in multiblock domain settings. The interface reflections due to the coupling (SBP-SAT) dominate in domain decomposition settings and they are of the same order as the SBP operator used in the interior domain. READ MORE

  3. 17. Simulation of Wave Propagation in Discontinuous Media and Complex Geometries

    University essay from Institutionen för informationsteknologi

    Author : Kristoffer Virta; [2010]
    Keywords : ;

    Abstract : A strictly stable high order finite difference (HOFD) scheme for the scalar wave equation with discontinuous coefficients corresponding to inhomogeneity in the underlying media is constructed using summation - by - parts (SBP) operators. The domain of the equation is allowed to be complex in the sense that it can not be smoothly mapped from the unit square. READ MORE
