The purpose of this paper is to give a unified investigation of a class of nonoverlapping domain decomposition methods for solving second-order elliptic problems in two and three dimensions. The methods under scrutiny fall into two major categories: the substructuring--type methods and the Neumann--Neumann-type methods. The basic framework used for analysis is the parallel subspace . In this paper, certain iterative substructuring methods with Lagrange multipliers are considered for elliptic problems in three dimensions. The algorithms belong to the family of dual-primal finite element tearing and interconnecting (FETI) methods which recently have been introduced and analyzed successfully for elliptic problems in the plane.
This two-volume book presents outcomes of the 7th International Conference on Soft Computing for Problem Solving, SocProS This conference is a joint technical collaboration between the Soft Computing Research Society, Liverpool Hope University (UK), the Indian Institute of Technology Roorkee, the South Asian University New Delhi and the National Institute of Technology Silchar, and. Chapter 4 discusses a large class of methods using nonoverlapping domains, also called substructuring methods. Following a historical introduction, the first section presents direct substructuring methods and Schur complements. An example describing a large-scale computation for an off shore oil production platform follows.
1. Introduction. The Wittrick–Williams (W–W) algorithm,, is a reliable and efficient tool to obtain eigenvalues (natural frequencies in free vibration problems or critical load factors in buckling problems) of transcendental eigenproblems to any required accuracy, in contrast to alternative methods which can miss eigenvalues. The algorithm does not directly compute the eigenvalues, but. This book is a collection of papers presented at the 23rd International Conference on Domain Decomposition Methods in Science and Engineering, held on Jeju Island, Korea on July , Domain decomposition methods solve boundary value problems by splitting them into smaller boundary value problems on subdomains and iterating to coordinate.

Substructuring preconditioner for parabolic problems by the mortar method Article (PDF Available) in International Journal of Numerical Analysis and Modeling 5(4) January with 25 Reads. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): 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 iteratively with a Neumann-Dirichlet preconditioner. Substructuring Methods For Parabolic Problems. By 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, Substructuring methods for parabolic problems. book 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.

For comparison, the frame will be analyzed with four approaches to extract the first 20 eigensolutions of the global structure.
In the first approach, the frame is analyzed by the original Kron's substructuring method, in which the whole eigensolutions of each substructure are calculated to assemble the primitive primitive matrices have the size of × and are solved with.Substructuring methods for parabolic problems, in: Fourth International Symposium on Domain Decomposition Methods for Partial Differential Equations Jan
