An Augmented Lagrangian Mixed Finite Element Scheme for Saddle Point Problems
نویسنده
چکیده
An augmented Lagrangian iterative scheme for mixed nite element methods is proposed and analyzed in an abstract framework. This framework is put in a general and computationally eecient fashion, and is based on the idea of iteratively penalizing the mixed nite element scheme. It is shown that the scheme has geometrical convergence.

A Three-field Augmented Lagrangian Formulation of Unilateral Contact Problems with Cohesive Forces
We investigate unilateral contact problems with cohesive forces, leading to the constrained minimization of a possibly nonconvex functional. We analyze the mathematical structure of the minimization problem. The problem is reformulated in terms of a three-field augmented Lagrangian, and sufficient conditions for the existence of a local saddle-point are derived. Then, we derive and analyze mixe...
متن کاملNull Space Algorithms for Solving Augmented Systems arising in the Mixed Finite Element Approximation of Saddle Point Problems
We use a Null Space algorithm approach to solve augmented systems produced by the mixed finite element approximation of saddle point problems. We compare the use of an orthogonal factorization technique for sparse matrices with the use of a sparse Gaussian elimination for the computation of the Null Space. Finally, we present the results of the numerical tests which we performed on selected pro...
متن کاملAn Augmented Lagrangian Method for Identifying Discontinuous Parameters in Elliptic Systems
The identification of discontinuous parameters in elliptic systems is formulated as a constrained minimization problem combining the output least squares and the equation error method. The minimization problem is then proved to be equivalent to the saddle-point problem of an augmented Lagrangian. The finite element method is used to discretize the saddle-point problem, and the convergence of th...
متن کاملNumerical methods for the Stokes and Navier-Stokes equations driven by threshold slip boundary conditions
In this article, we discuss the numerical solution of the Stokes and Navier-Stokes equations completed by nonlinear slip boundary conditions of friction type in two and three dimensions. To solve the Stokes system, we first reduce the related variational inequality into a saddle point-point problem for a well chosen augmented Lagrangian. To solve this saddle point problem we suggest an alternat...

In this paper we develop a numerical procedure using finite element and augmented Lagrangian meth-ods that simulates electro-mechanical pull-in states of both cantilever and fixed beams in microelectromechanical systems (MEMS) switches. We devise the augmented Lagrangian methods for the well-known Euler-Bernoulli beam equation which also takes into consideration of the fringing effect of electr...
