[petsc-users] Extracting parts of DMPLEX mesh

[Swarnava Ghosh]

Hi PETSc,

I am trying to extract parts of a distributed dmplex mesh in each MPI
process. For each process, the mesh to extract is the part of the mesh
owned by that process and the parts of the mesh owned by a few neighbor
processes, and the extracted mesh is stored locally to that process. For
each process, I know what the ranks of the neighbor processes are.

Would you please share any ideas on how to go about this?

Sincerely,
SG
