A subspace correction method for discontinuous Galerkin discretizations of linear elasticity equations
Blanca Ayuso de Dios, Ivan Georgiev, Johannes Kraus +1
We study preconditioning techniques for discontinuous Galerkin discretizations of isotropic linear elasticity problems in primal (displacement) formulation. We propose subspace cor…
A Block Solver for the Exponentially Fitted IIPG-0 method
Blanca Ayuso de Dios, Ariel Lombardi, Paola Pietra +1
We consider an exponentially fitted discontinuous Galerkin method and propose a robust block solver for the resulting linear systems.
Multigrid Preconditioner for Nonconforming Discretization of Elliptic Problems with Jump Coefficients
Blanca Ayuso De Dios, Michael Holst, Yunrong Zhu +1
In this paper, we present a multigrid preconditioner for solving the linear system arising from the piecewise linear nonconforming Crouzeix-Raviart discretization of second order e…
Analysis of two-level method for anisotropic diffusion equations on aligned and non-aligned grids
Guozhu Yu, Jinchao Xu, Ludmil Zikatanov
This paper is devoted to the multigrid convergence analysis for the linear systems arising from the conforming linear finite element discretization of the second order elliptic equ…
