Detailed Description

This class implements an algebraic multigrid (AMG) preconditioner based on the Trilinos MueLu implementation, which is a black-box preconditioner that works well for many PDE-based linear problems. The interface of PreconditionerAMGMueLu is the same as the interface of PreconditionerAMG except for the higher_order_elements parameter which does not exist in PreconditionerAMGMueLu.

Note: You need to configure Trilinos with MueLU support for this preconditioner to work.; At the moment 64bit-indices are not supported.

Warning: This interface should not be considered as stable.
