[petsc-users] DMPlex submesh and Boundary mesh

[Dharmendar Reddy]

Hello,
          I see that i can extract submesh from a DM object using

DMPlexCreateSubmesh(DM dm, const char vertexLabel[], DM *subdm)


Can i request for an interface where i can extract

DMPlexCreateSubmesh(DM dm, const char vertexLabel[], PetscInt value, DM *subdm)

I have to create a lot of subdms typically few hundred. I can always create
required number of unique labels, but i was wondering if i can group them
with single label but different values of strata.

How do i extract boundary  nodes of a given mesh ? For example i have a
triangular mesh on square boundary, I need to mark the nodes on the square
boundary.

Thanks
Reddy
