چکیده
In this note, we explain the implementation detail of multigrid methods. We will use the approach by space decomposition and subspace correction method; see Chapter: Subspace Correction Method and Auxiliary Space Method. The matrix formulation will be obtained naturally, when the functions’ basis representation is inserted. We also include a simplified implementation of multigrid methods using finite difference approach. To distinguish functions and vectors, we use boldface letter for a matrix representation of an operator or a vector representation of a function.

Parallel linear algebra and the application to multigrid methods
We explain a general model for a parallel linear algebra. All algebraic operations and parallel extensions are defined formally, and it is shown that in this model multigrid methods on a distributed set of indices can be realized. This abstract formalization leads to an automatic realization of parallel methods for time-dependent and nonlinear partial differential equations and the solution of ...
متن کاملModel Problems for the Multigrid Optimization of Systems Governed by Differential Equations
We discuss a multigrid approach to the optimization of systems governed by differential equations. Such optimization problems appear in many applications and are of a different nature than systems of equations. Our approach uses an optimization-based multigrid algorithm in which the multigrid algorithm relies explicitly on nonlinear optimization models as subproblems on coarser grids. Our goal ...
متن کاملRelaxation Schemes for Chebyshev Spectral Multigrid Methods
SUMMARY Two relaxation schemes for Chebyshev spectral multigrid methods are presented for elliptic equations with Dirichlet boundary conditions. The rst scheme is a pointwise-preconditioned Richardson relaxation scheme and the second is a line relaxation scheme. The line relaxation scheme provides an eecient and relatively simple approach for solving two-dimensional spectral equations. Numerica...
متن کاملMultigrid-Based Optimal Shape and Topology Design in Magnetostatics
The paper deals with an efficient solution technique to large– scale discretized shape and topology optimization problems. The efficiency relies on multigrid preconditioning. In case of shape optimization, we apply a geometric multigrid preconditioner to eliminate the underlying state equation while the outer optimization loop is the sequential quadratic programming, which is done in the multil...
