An approximate BDDC preconditioner

Abstract

The balancing domain decomposition by constraints (BDDC) preconditioner requires direct solutions of two linear systems for each substructure and one linear system for a global coarse problem. The computations and memory needed for these solutions can be prohibitive if any one system is too large. We investigate an approach for addressing this issue based… (More)
