[Trilinos-Users] Epetra_CrsMatrix and AztecOO

I had a problem in using a Epetra_CrsMatrix to define a linear problem and
solving the problem with AztecOO, e.g., with programs similar to
Epetra_CrsMatrix A(Copy, Map, numNz);
// fill the matrix
I got the following error
AZ_extract_comm_info: Received elements must be stored after
all XXX local elements
and then figured out that AztecOO requires a zero free diagonal. I
added diagonal entries to A and then the solution followed smoothly.
What about Multiply member function(s) of the Epetra_CrsMatrix class?
Do I have to specify diagonal entries for these functions to compute
