[Trilinos-Users] [EXTERNAL] Anasazi solver with ML preconditioner won't converge

[Raymond Tuminaro]

Andris,
    I can't tell if it is an ML problem or an Anasazi problem. I've actually never combined ML with Anasazi ... I'm not 
sure who would be best to address this?  Could you add the following after the SetDefaults() line in your code:

precOptions.set("ML output",10);


This should at least get ML to spit out some output. Could you tell us more about where your matrix comes from. Is it a 
discretization of a PDE system? If so, what type of PDE?
