I had some experience of using PETSc in Fortran. In Fortran, I used the following subroutines: call DMPlexCreateNaturalVector(dm, natural, ierr) call DMPlexNaturalToGlobalBegin(dm,natural,X,ierr) call DMPlexNaturalToGlobalEnd(dm,natural,X,ierr) However, I found there are no such interfaces in petsc4py. Can you advise me on how to get the global vector in natural order with DMPLEX in petsc4py?
