[Trilinos-Users] non local matrix in Epetra_FECrsMatrix

[Radu Popescu]

Hello,

I'm working on a FEM code where I use the Epetra_FECrsMatrix class. I'm
building an Epetra_FECrsGraph object first and building the matrix with the
constructor that takes the FECrsGraph object.

I'm interested in using the approach where a non local graph is built
inside the FECrsGraph, which then causes a CrsMatrix for non local DOFs to
be embedded inside the FECrsMatrix.

I've noticed, though, that enabling this option gives different results
(the number of non zero elements in the final matrix is different in the
two cases).

Is anybody already using this approach, or is it deprecated?

Thank you,
Radu Popescu
