[petsc-users] Questions about the physical groups

[Jian Zhang - 3ME]

Hi all,

I have a mesh file where I defined a physical group named "volume" whose id is 0.

For DMPlex, I know that I can use this id (0) to access this physical group. Here I would like to ask that is it possible to use the physical group name "volume" to achieve this in DMPlex. Thank you very much.

Bests,

Jian
