[petsc-users] vtkviewer with cloned dm

[Dharmendar Reddy]

Hello,
         Looks like the call DMGetCoordinatesLocal(clonedDM,coords,ierr) is
giving a null coords Vec. DMView on clonedDM is printing the expected
information

Mesh in 2 dimensions:
  0-cells: 9
  1-cells: 16
  2-cells: 8
Labels:
  marker: 2 strata of sizes (16, 5)
  depth: 3 strata of sizes (9, 16, 8)

the original dm is created using DMPlexCreateBoxMesh.
