A Numerical Study of FETI Algorithms for Mortar Finite Element Methods
The Finite Element Tearing and Interconnecting (FETI) method is an iterative substructuring method using Lagrange multipliers to enforce the continuity of the nite element solution across the subdomain interface. Mortar nite elements are nonconforming nite elements that allow for a geometrically nonconforming decomposition of the computational domain into subregions and, at the same time, for t...
متن کاملA FETI-DP Formulation of Three Dimensional Elasticity Problems with Mortar Discretization
Abstract. In this paper, a FETI-DP formulation for the three dimensional elasticity problem on non-matching grids over a geometrically conforming subdomain partition is considered. To resolve the nonconformity of the finite elements, a mortar matching condition on the subdomain interfaces (faces) is imposed. By introducing Lagrange multipliers for the mortar matching constraints, the resulting ...
متن کاملA FETI-DP Formulation for Compressible Elasticity with Mortar Constraints
A FETI-DP formulation for three dimensional elasticity problems on non-matching grids is considered. To resolve the nonconformity of the finite elements, a mortar matching condition is imposed on subdomain interfaces. The mortar matching condition are considered as weak continuity constraints in the FETIDP formulation. A relatively large set of primal constraints, which include average and mome...
متن کاملA Feti-dp Algorithm for Elasticity Problems with Mortar Discretization on Geometrically Non-conforming Partitions
Abstract. In this paper, a FETI-DP formulation for three dimensional elasticity on non-matching grids over geometrically non-conforming subdomain partitions is considered. To resolve the nonconformity of the finite elements, a mortar matching condition is imposed on the subdomain interfaces (faces). A FETI-DP algorithm is then built by enforcing the mortar matching condition in dual and primal ...
متن کاملParallel scalability of a FETI–DP mortar method for problems with discontinuous coefficients
We consider elliptic problems with discontinuous coefficients discretized by FEM on non-matching triangulations across the interface using the mortar technique. The resulting discrete problem is solved by a FETI–DP method using a preconditioner with special scaling described in Dokeva, Dryja and Proskurowski [to appear]. Experiments performed on hundreds of processors show that this FETI–DP mor...
