[petsc-users] A partition of DMPlex mesh similar to what DMDA provides?

[liluo]

Dear PETSc developers,


I’m using DMPlex to manage an unstructured mesh. However, in my case, the input mesh is actually a structured tetrahedral mesh, and its geometric domain is just a simple box.


Is there any PETSc functionality or recommended approach to obtain a partition similar to what DMDA provides—i.e., a simple Cartesian block partition—when working with such a mesh in DMPlex?

Any guidance or best practices would be greatly appreciated.


Thank you!


Bests,

Li Luo
