[Trilinos-Users] Question about the Aztec00 interface

[Moffat, Harry K]

When solving
      AX =b
with Aztec00, what type of Epetra_MultiVector objects do you have to feed into the Azcte00 constructor?

1  Can you feed in X and B objects whose Epetra_Maps objects consist of  just owned elements?
2  Can you feed in X and B objects whose Epetra_Maps consist of  just owned and "ghost" elements? i.e., ghost elements are elements which are needed to complete the columns of A.
3  Can you feed in X which consists of elements and ghost elements and B which consists of just owned elements.

The question comes about because I didn't see this answered in the doxygen documentation for Aztec00. And, I'm getting some squirrelish behavior that I can't seem to track down.

Thanks in advance,
Harry Moffat
