Substructuring Methods For Parabolic Problems. By Maksymilian Dryja. Abstract. Domain decomposition methods without overlapping for the approximation of parabolic problems are considered. Two kinds of methods are discussed. In the first method systems of algebraic equations resulting from the approximation on each time level are solved Author: Maksymilian Dryja. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Abstract. We study substructuring preconditioners for the linear system aris-ing from the discretization of parabolic problems when the mortar method is applied. By using a suitable non standard norm equivalence we build an effi-cient edge block preconditioner and we prove a polylogarithmic bound for the condition. This book serves as an introduction to this subject, with emphasis on matrix formulations. The topics studied include Schwarz, substructuring, Lagrange multiplier and least squares-control hybrid formulations, multilevel methods, non-self adjoint problems, parabolic equations, saddle point problems (Stokes, porous media and optimal control), non-matching grid. This book provides insight in the mathematics of Galerkin finite element method as applied to parabolic equations. The approach is based on first discretizing in the spatial variables by Galerkin's method, using piecewise polynomial trial functions, and then applying some single step or multistep time stepping method.

  Abstract. We present and analyze waveform relaxation variants of the Dirichlet-Neumann and Neumann-Neumann methods for parabolic problems. These methods are based on a non-overlapping spatial domain decomposition, and each iteration involves subdomain solves with Dirichlet boundary conditions followed by subdomain solves with Neumann boundary conditions.
