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!
