Hi,
Over the past few months, I have implemented dmplex/section in my
preexisting finite element code. We already had our own implementations
for things like the finite element space, boundary conditions,
projections, etc, so I am mostly using dmplex/section at its lowest
level; no DT/DS
Hi,
In my code, I have a separate preprocessing script that I usually run in
serial to set up various things for my solver. One of the things I want
the preprocessor to do is setup everything related to the DMPlex, and
then I write it out to an HDF5 file to be read in the main solver. In
the
Hi,
At some point, I would like to export my distributed DM along with an
associated scalar field corresponding to the process rank for which each
point is owned. I know that what I need is the partition section, which
is more or less identical to Fig. 6 in Knepley and Karpeev (2009). I was

Another option is to use DMPlex for your mesh. It will give you the
dual if you want.
Thanks,

Hi,
I am trying to use the function MatMeshToCellGraph. I currently have a
matrix that holds the cell connectivity of simplex elements. So it is a
numCells x 3 matrix where the row corresponds to the cell number and the
column is a vertex of that cell. To use this function, it appears I need
