Nonoverlapping Domain Decomposition Methods for Saddle Point ProblemsÌý
Ìý

Ìý

Two widely used nonoverlapping domain decomposition methods BDDC (Balancing domain decomposition by constraints) Ìýand FETI-DP (Dual-primal finite element tearing and interconnecting) are studied for the systems of linear equations arising from the mixed finite element approximation of elliptic and incompressible Stokes equations. In this talk, several recently developed techniques such as deluxe scaling, adaptive coarse spaces, and a

framework for continuous pressure discretization will be Ìýdiscussed. Condition number estimate of these algorithms will be provided and numerical experiments will demonstrate the performance of the discussed algorithms.
