Hey there, thanks for the response. I made the recommended change to trilinos_sparse_matrix.cc, and the corresponding test code returns the appropriate output. However, I'm still getting an issue in my particular case. It's improved in that the resulting matrix is now square and the dimensions agree with the serial case, but the contents still do not match.
I introduced the new code into deal.ii version 8.3.0, I'm hoping to avoid updating to 8.4 for as long as I can. Could there be some other bug in the multiplication step in trilinos_sparse_matrix.cc? If not, I will try updating to the newest version and repeat the change there. -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see https://groups.google.com/d/forum/dealii?hl=en --- You received this message because you are subscribed to the Google Groups "deal.II User Group" group.
