[Trilinos-Users] Is IFPACK a valid option for an AZTECOO preconditioner?

[Heroux, Michael A]

Ernesto,

All Ifpack preconditioners implement the Epetra_Operator interface and can therefore be registered via the AztecOO SetPrecOperator method.  You must fully construct the preconditioner prior to using it with AztecOO and you are responsible for the preconditioner when done with it.

The Ifpack user guide (Chapter 5) shows examples using Ifpack with AztecOO.

If so, how can one set such option?

Thanks,
