27: . PetscViewerVTKWriteFunction - function to write this Vec
28: . fieldnum - which field of the DM to write (PETSC_DEFAULT if the whle vector should be written)

31: - vec - Vec from which to write
33: Note:
34: This routine keeps exclusive ownership of the Vec. The caller should not use or destroy the Vec after adding it.
