So this turned out to be a bug in my own code after I made the original
change in trilinos_sparse_matrix.cc. When I was constructing the sparsity
patterns for the matrices using DoFTools::make_sparsity_pattern, there is a
flag I had set keep_constrained_dofs = false. Setting this flag to true ha
Hello Bruno,
Sorry for the vagueness, I was not confident if this was an actual bug in
deal.ii (I've never encountered one before!). Here I've attached a
bare-bones version of my code which reproduces the bug I'm encountering. I
basically look at 4 cases:
1) deal.ii's TrilinosWrappers::SparseM

post. So I've at least ruled out that it's not an issue specific to my
version number.

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
Sounds like we ran into the same problem
https://github.com/dealii/dealii/pull/2536, although is also experienced
this issue in serial.
