Multilevel Preconditioning for Finite Volume Element Methods
نویسندگان
چکیده
We consider precondition of linear systems resulting from the finite volume element method (FVEM) for elliptic boundary value problems. With the help of the interpolation operator from a trial space to a test space and the operator induced by the FVEM bilinear form, we show that both wavelet preconditioners and multilevel preconditioners designed originally for the finite element method for the same boundary value problems can be used to precondition the finite volume element matrices. We prove that such preconditioners ensure that the resulting coefficient matrix has a uniformly bounded condition number. We also present four numerical examples to confirm the theoretical result.

Hybrid Finite Element and Volume Integral Methods for Scattering Using Parametric Geometry
In this paper we address several topics relating to the development and implementation of volume integral and hybrid finite element methods for electromagnetic modeling. Comparisons with the finite elementboundary integral method are given in terms of accuracy and computing resources. We also discuss preconditioning, parallelization of the multilevel fast multipole method and propose higher-ord...
متن کاملLocal Multilevel Methods for Adaptive Nonconforming Finite Element Methods
In this paper, we propose a local multilevel product algorithm and its additive version for linear systems arising from adaptive nonconforming finite element approximations of second order elliptic boundary value problems. The abstract Schwarz theory is applied to analyze the multilevel methods with Jacobi or Gauss-Seidel smoothers performed on local nodes on coarse meshes and global nodes on t...
متن کاملCBS constants for multilevel splitting of graph-Laplacian and application to preconditioning of discontinuous Galerkin systems
The goal of this work is to derive and justify a multilevel preconditioner of optimal arithmetic complexity for symmetric interior penalty discontinuous Galerkin finite element approximations of second order elliptic problems. Our approach is based on the following simple idea given in [R.D. Lazarov, P.S. Vassilevski, L.T. Zikatanov, Multilevel preconditioning of second order elliptic discontin...
متن کاملGeneralized Aggregation-Based Multilevel Preconditioning of Crouzeix-Raviart FEM Elliptic Problems
Preconditioners based on various multilevel extensions of two-level finite element methods (FEM) are well-known to yield iterative methods of optimal order complexity with respect to the size of the system, as was first shown by Axelsson and Vassilevski [4]. The derivation of optimal convergence rate estimates in this context is mainly governed by the constant γ ∈ (0, 1) in the so-called Cauchy...
متن کاملMultigrid for the Mortar Finite Element Method
A multigrid technique for uniformly preconditioning linear systems arising from a mortar finite element discretization of second order elliptic boundary value problems is described and analyzed. These problems are posed on domains partitioned into subdomains, each of which is independently triangulated in a multilevel fashion. The multilevel mortar finite element spaces based on such triangulat...
