[petsc-users] If DMPLEX can be created from BDF mesh format?

[Mark Adams]

Hi Cheng,

Sorry for the late reply. I believe we only support reading .msh files in
DMPlex.
You can look at src/dm/impls/plex/tests/ex1.c as an example (testing input
parameters are in a large comment at the bottom of the file).
