Preconditioned Mixed Spectral Element Methods for Elasticity and Stokes Problems
Preconditioned iterative methods for the indefinite systems obtained by discretizing the linear elasticity and Stokes problems with mixed spectral elements in three dimensions are introduced and analyzed. The resulting stiffness matrices have the structure of saddle point problems with a penalty term, which is associated with the Poisson ratio for elasticity problems or with stabilization techn...
متن کاملIterative Substructuring Methods for Spectral Element Discretizations of Elliptic Systems. II: Mixed Methods for Linear Elasticity and Stokes Flow
Iterative substructuring methods are introduced and analyzed for saddle point problems with a penalty term. Two examples of saddle point problems are considered: the mixed formulation of the linear elasticity system and the generalized Stokes system in three dimensions. These problems are discretized with spectral element methods. The resulting stiiness matrices are symmetric and indeenite. The...
متن کاملPreconditioned iterative methods for Navier-Stokes control problems
PDE-constrained optimization problems are a class of problems which have attracted much recent attention in scientific computing and applied science. In this paper, we discuss preconditioned iterative methods for a class of Navier-Stokes control problems, one of the main problems of this type in the field of fluid dynamics. Having detailed the Oseen-type iteration we use to solve the problems a...
متن کاملStabilized Schemes for Mixed Finite Element Methods with Applications to Elasticity and Compressible Flow Problems
Stabilized iterative schemes for mixed nite element methods are proposed and analyzed in two abstract formulations. The rst one has applications to elliptic equations and incompressible uid ow problems, while the second has applications to linear elasticity and compressible Stokes problems. Convergence theorems are demonstrated in abstract formulations; applications to individual physical probl...
متن کاملMixed Finite Element Methods for Elliptic Problems*
This paper treats the basic ideas of mixed finite element methods at an introductory level. Although the viewpoint presented is that of a mathematician, the paper is aimed at practitioners and the mathematical prerequisites are kept to a minimum. A classification of variational principles and of the corresponding weak formulations and Galerkin methods—displacement, equilibrium, and mixed—is giv...
