Domain Decomposition for Heterogeneous Media
[chapter]
Lecture Notes in Computational Science and Engineering
Elliptic problems with multiscale coefficients have been studied to a great extent recently. Preconditioners based on standard domain decomposition methods often perform poorly when the variation of the coefficients inside the subdomains is large. In this paper we study the behaviour of domain decomposition methods based on linear coarsening for such problems and we also propose improved methods which use the notion of multiscale finite elements to define coarsening operators.
