Numerical Experiments for the Arnold-Winther Mixed Finite Elements for the Stokes Problem
نویسندگان
چکیده
The stress-velocity formulation of the stationary Stokes problem allows an Arnold–Winther mixed finite element formulation with some superconvergent reconstruction of the velocity. This local postprocessing gives rise to two reliable a posteriori error estimators which recover optimal convergence order for the stress error estimates. The theoretical results are investigated in numerical benchmark examples.

A Multigrid Preconditioner for the Mixed Formulation of Linear Plane Elasticity
In this paper, we develop a multigrid preconditioner for the discrete system of linear equations which results from the mixed formulation of the linear plane elasticity problem using the Arnold-Winther elements. This, in turn, can be reduced to the problem of finding a multigrid preconditioner for the form (·, ·)+(div ·,div ·) in the symmetric tensor space resulting from Arnold-Winther elements...
متن کاملA Robust Finite Element Method for Darcy-Stokes Flow
Finite element methods for a family of systems of singular perturbation problems of a saddle point structure are discussed. The system is approximately a linear Stokes problem when the perturbation parameter is large, while it degenerates to a mixed formulation of Poisson’s equation as the perturbation parameter tends to zero. It is established, basically by numerical experiments, that most of ...
متن کاملThe Arnold–Winther mixed FEM in linear elasticity. Part I: Implementation and numerical verification
Following some de Rham complex, Arnold and Winther have recently proposed a symmetric mixed finite element method (MFEM) in linear elasticity. This paper describes the implementation of the symmetric MFEM and its 30 30 local stress stiffness matrices and studies the implementation of the lowest-order scheme for general boundary conditions. Numerical experiments in model examples in computationa...
متن کاملFirst-Order System Least-Squares for Darcy-Stokes Flow
The subject of this paper is a first-order system least-squares formulation for the Stokes equation which remains uniformly valid in the limit of vanishing viscosity. For this so-called Darcy-Stokes flow problem we establish continuity and coercivity of the corresponding least-squares functional in appropriate norms. Two types of finite element spaces for the approximation of the velocity field...
متن کاملSemilinear Mixed Problems on Hilbert Complexes and Their Numerical Approximation
Arnold, Falk, and Winther recently showed [Bull. Amer. Math. Soc. 47 (2010), 281–354] that linear, mixed variational problems, and their numerical approximation by mixed finite element methods, can be studied using the powerful, abstract language of Hilbert complexes. In another recent article [arXiv:1005.4455], we extended the Arnold–Falk–Winther framework by analyzing variational crimes (a la...
