1. 1. Convergence Rate of the Dirichlet-Neumann Algorithm for Coupled Poisson Equations

   Master-uppsats, Lunds universitet/Matematik LTH

   Författare :Morgan Görtz; [2019]
   Nyckelord :Dirichlet-Neumann; Dirichlet-Neumann algorithm; Poisson equation; convergence rate; finite element method; finite volume method; finite difference method; Mathematics and Statistics;

   Sammanfattning : This thesis presents and tests the convergence rate of the Dirichlet-Neumann algorithm for two Poisson equations coupled by transmission boundary conditions. Three second order discretisation methods are used when analyzing the convergence: standard equidistant finite difference, standard adaptive linear finite element, and standard adaptive finite volume discretisation of Poisson's equation.

3. 2. Parallelization Of The GMRES Method

   Kandidat-uppsats, Lunds universitet/Matematik LTH

   Författare :Morgan Görtz; [2016]
   Nyckelord :GMRES; MPI; Technology and Engineering;

   Sammanfattning : In this thesis a GMRES method is constructed and tested. The method is implemented in a C++ program with the MPI protocol to make it parallel. The parallel parts of this program are discussed in detail, especially the communication and the partitioning of the data between the processes. LÄS MER
