Schwarz Analysis of an Iterative Substructuring Algorithm for P1 Nonconforming Finite Elements
We give an iterative substructuring algorithm for the P1 nonconforming nite element approximation of a second order elliptic problem in dimension two. The algorithm and its convergence analysis are based on an abstract framework of the Schwarz method. A bound is established for the condition number of this iterative method which grows only logarithmically with the number of degrees of freedom. ...
متن کاملA Neumann-Neumann preconditioned iterative substructuring approach for computing solutions to Poisson's equation with prescribed jumps on an embedded boundary
In multifluid problems with surface tension the fluid pressure and its derivative are discontinuous at fluid interfaces. We present a Cartesian grid embedded boundary method for numerically resolving these discontinuities in which we use Neumann–Neumann preconditioned iterative substructuring to solve the governing equations. We validate this method by computing several well-known Poisson probl...
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 کاملA Parallel Implementation of an Iterative Substructuring Algorithm for Problems in Three Dimensions
Numerical results from a parallel implementation of an iterative substructuring algorithm are reported. The algorithm is for solving scalar, self-adjoint elliptic partial diierential equations in three dimensions. Results are given for two variants of the algorithm. In the rst variant, exact interior solvers are used; in the second, one multigrid V-cycle is used to approximately solve the inter...
متن کاملIterative Substructuring Methods for Indoor Air Flow Simulation
The numerical simulation of turbulent indoor-air flows is performed using iterative substructuring methods. We present a framework for coupling eddyviscosity turbulence models based on the non-stationary, incompressible, nonisothermal Navier-Stokes problem with non-isothermal near-wall models; this approach covers the k/ǫ model with an improved wall function concept. The iterative process requi...
