Here is the entire error. I was interpreting the error was the “Nonconforming
object size”, which is the error I was reporting. I will research the error 60
in Slepc, thank you!

No, that's not what you want. You need to partition the columns in the same way as you partition the vectors you want to multiply the matrix by. We generally partition the vectors in the same way as the rows of the matrix, and so then you also have to choose the same partitioning for the columns
You said “the local number of columns also needs to add up to the global
number of columns” but my desired layout is local_num_columns ==
global_num_columns.
No, that's not what you want. You need to partition the columns in the same
way as you partition the vectors you want to multiply

This way I can freely use bubble functions and only construct local K and F of

support cell->get_dof_indices(local_dof_indices). Is there any way to call the

You are right. I am not bounded by the memory at this moment. The only

Hi W and Jean-Paul,
Thanks again for your suggestions.
I realized that the bubble functions that I prefer are actually the shape
functions from other standard elements. Thus I only need to define two sets
of FE (i.g. FE_1 and FE_b). Then I use the iterator from triangulation as

Dear Behrooz,
The problem here is that your Trilinos installation includes the
SEACASChaco package. We'd discovered that there's a common global symbol
that both ADOL-C and Trilinos-SEACASChaco emit, which causes some very
strange issues when using ADOL-C. Naturally, we had to make sure that

Hi W.,
Apologies for not asking a specific question. Your help with the SparseMatrix
constructor still left me confused and I was hoping for clarity. ( To answer
your question, the code ran without error but the error came back once I tried
to use Slepc. )
You said “the local number of
Dear Wolfgang,
Thank you for your response. I am working on phase-stability in materials,
for smooth initial conditions it produces the correct phase but for random
initialization it produces a phase which I am not expecting. The phases are
every sensitive to the initial-conditions used. If I
