<div>Miguel,</div>
<div> One possible way is to store the global numbering of any edge/vertex in the "component" attached to it. Once the mesh gets partitioned, the components are also distributed so you can easily retrieve the global number of any edge/vertex by accessing
its component. This is what is done in the DMNetwork example pf.c although the global numbering is not used for anything. </div>

</div>
<div>I do not completely understand the question.</div>
<div><br>
</div>
<div>If you want a partition of the edges, you can use DMPlexCreatePartition() and its friend DMPlexDistribute(). What</div>
<div>are you trying to do?</div>

<div dir="ltr">Hi
<div><br>
</div>
<div>I noticed that the routine DMNetworkGetEdgeRange() returns the local indices for the edge range. Is there any way to obtain the global indices? So if my network has 10 edges, the processor 1 has the 0-4 edges and the processor 2, the 5-9 edges, how can
I obtain this information?</div>

<div>One of the points of DMPlex is we do not require a global numbering. Everything is numbered</div>
<div>locally, and the PetscSF maps local numbers to local numbers in order to determine ownership.</div>
<div><br>
</div>
<div>If you want to create a global numbering for some reason, you can using DMPlexCreatePointNumbering().</div>
<div>There are also cell and vertex versions that we use for output, so you could do it just for edges as well.</div>

<div> Thanks,</div>
