On Inexact Solvers for the Coarse Problem of BDDC

Dohrmann, Clark R.; Pierson, Kendall H.; Widlund, Olof B.

In this study, we present Balancing Domain Decomposition by Constraints (BDDC) preconditioners for three-dimensional scalar elliptic and linear elasticity problems in which the direct solution of the coarse problem is replaced by a preconditioner based on a smaller vertex-based coarse space.
