Hi all,
I would like to bring your attention to the publication
The deal.II finite element library: design, features, and insights
Computers & Mathematics with Applications, vol. 81, pages 407-422, 2021.
https://doi.org/10.1016/j.camwa.2020.02.022
that just got published. As a user/developer of
Hi there,
If the dynamic sparsity pattern is distributed to all the processes, should
I expect to have the full sparsity pattern returned from the
distribute_sparsity_pattern function? In other words, is the number of
rows of dsp the local number of rows before the distribute function call

Hi,
No, the problem is much simpler. You have to reorganize your
CMakeLists.txt so that you search for your libraries and add them to
your link interface after the PROJECT() call and after the
DEAL_II_INVOKE_AUTOPILOT CALL(). It is simplest to put everything last:
# The default CMakeLists.txt
Okay, that makes sense.
The PETSc error I am getting is the sum of the local lengths (10200) is
larger than the global length (1020) so I think I need to just read the
documentation more because it looks like I am just not using the API
appropriately.
Thank you,
Zachary

Animesh,
I did exactly as you suggested. My package export cmake configurations. I am
getting the following error and cant figure out the reason. It is not able to
link the executable with the package.

That's true for cells but not for degrees of freedom. There may be DoFs that
are located on the faces between locally owned and ghost cells. These may be

Sorry, I should say the relevant elements are the same as the locally
owned. I am pretty sure I don't need to do any communications in building
my matrices. Yes there will always be ghost elements with multiple MPI
processes.
I think I need to look more at the IndexSet and make sure I am usi

Are there not always ghost elements if you have more than one MPI p
Hi W.,
Thank you for your suggestion, this does seem helpful for me to tailor
things for my needs. One clarification, is locally_relevent =
locally_owned if there are no ghost elements? I am trying to debug the
PETSc sparse matrix reinit segfault, I am not setting things up correctly

Dear all
I have downloaded deal.II.9.2.0-v3.dmg and installed on MacBook Pro
(Catalina, Xcode 12.3). In terminal I use : module load dealii and
everything went well.
Initially there was a problem with the compiler path in the CMakeCache.txt
which I fixed it. Then when I tried to compile and
What I understood after struggling through the issue is that my
cmakelists.txt is in autopilot style. In the autopilot style, it doesn't
build the executable right away after doing "cmake .". It builds the
executable after I run "make" command (as per my observation). I think this
is why it is
