[Trilinos-Users] AztecOO as smoother for ML from Stratimikos

[Chris Siefert]

Alberto,

ML has no problem with using AztecOO as a smoother.  However, there is 
no Stratimikos wrapper for this functionality.

Could you use to Stratimikos::DefaultLinearSolver builder objects and some of your own wrapper code to construct this?  Does ML already have built-in support to use AztecOO internally?  This might be more of question for the ML developers.
