[petsc-users] vertices on the boundary of a DMPLEX mesh

[Swarnava Ghosh]

Dear PETSc team,

I had the following question related to DMPLEX.
I have a dmplex mesh created through DMPlexCreateFromCellList. I want to
find out all the vertices that are on the mesh boundary. What is the best
way to do this?

Thank you,
SG
