<div class="PlainText">Hi,<br>
<br>
I just noticed that b6b5caf99979f50a7774afdccea5ca5661fc1203 Merge branch 'knepley/feature-hybrid-mass' into ‘main’ seems to have introduced a bug<br>
<br>
See the attached example (a very simple update of src/dm/impls/plex/tests/ex98.c)<br>
When calling DMGetMatrix, I get the following error:<br>
[0]PETSC ERROR: --------------------- Error Message --------------------------------------------------------------<br>

<br>
<br>
Do I now need to use DS in order to use duplex and sections?<br>
<br>
Regards,<br>
Blaise<br>
