[Trilinos-Users] Epetra_CrsMatrix::InsertGlobalValues

[Antonella Longo]

I insert a fixed number (1.0) in a specific position (row1,col1) of
an Epetra_CrsMatrix with the function InsertGlobalValues.
The problem is that more than one PID owns the (row1,col1) position,
so that when i call the function InsertGlobalValues for the (row1,col1)
position
each PID gives its contribution. As a result, after the fillComplete call
all these contributions will sum up, resulting in a number greater than 1
in position (row1,col1).
I also tried with the ReplaceGlobalValues function, but also these
contributions
are summed up with the fillComplete call.

Is there any way to prevent this problem?
