<p>Hmm, that's a bit weird. I haven't
modified the test code - I checked the
file date to make sure. I also tried
deleting my PETSc build dir and rebuilding
it, then rebuilding the test code. I still
get the error if I run on 2 ranks with
-dm_mat_type (or -mat_type) baij or
mpibaij, but it's fine on aij or mpiaij.</p>
<p>My actual (non-test) code is however
working ok now, in serial or parallel. So
I don't think this should hold up merging
your bugfix.<br>

<p>Thanks very much, that does
appear to fix the bug when I
run my test program in serial.</p>
<p>If I run it on 2 processes,
it is OK with AIJ matrix type,
but with BAIJ I get an error
(see below). Is there another
problem, or I am doing
something else wrong?</p>

<p>hi,</p>
<p>I've been trying
creating a matrix
with
DMCreateMatrix()
and then adding
extra blocks of
nonzeros into it
using
MatSetValuesBlocked(),
but getting some
unexpected results
if I set the
matrix type to
BAIJ. It seems to
behave as expected
if I use matrix
type AIJ.</p>
<p>I've attached a
minimal example
program. It reads
in the DMPlex from
file, sets up a
section on it,
creates a matrix
(blocksize 2) and
then inserts a
single 2x2 block
at global block
indices (0,7). It
views the matrix
before and after
the insertion.<br>
</p>
<p>If I run with
"-dm_mat_type aij"
it gives the
expected results,
but with
"-dm_mat_type
baij" it doesn't -
e.g. if run in
serial, it adds
the new nonzeros
in the right place
but also adds a
whole lot of other
duplicated entries
in block row 0.<br>
</p>
<p>Is there
something I'm not
understanding
about BAIJ, or
about
MatSetValuesBlocked()?
or possibly some
other mistake?<br>
</p>

You can call
MatSetOption(mat,MAT_NEW_NONZERO_LOCATION_ERR)
then insert the
new values. If it
is just a handful
of new insertions
the extra time
should be small.
<div><br>
</div>
<div> Making a
copy of the
matrix won't
give you a new
matrix that is
any faster to
insert into so
best to just use
the same matrix.</div>

I have a Jacobian matrix created using DMCreateMatrix(). What would be
the best way to add extra nonzero entries into it?
I'm guessing that DMCreateMatrix() allocates the storage so the nonzero
structure can't really be easily modified. Would it be a case of
creating a new matrix, copying the nonzero entries from the original one
and then adding the extra ones, before calling MatSetUp() or similar? If
so, how exactly would you copy the nonzero structure from the original
matrix?
Background: the flow problem I'm solving (on a DMPlex with finite volume
method) has complex source terms that depend on the solution (e.g.
pressure), and can also depend on other source terms. A simple example
is when fluid is extracted from one location, with a pressure-dependent
flow rate, and some of it is then reinjected in another location. This
can result in poor nonlinear solver convergence. I think the reason is
that there are effectively missing Jacobian entries in the row for the
reinjection cell, which should have an additional dependence on the
solution in the cell where fluid is extracted.
