XDMF's 3DRectMesh == VTK's vtkRectilinearGrid, in which you case you specify an X array, Y array and a Z array.
3DSMesh == vtkStructuredGrid, in which case you specify X,Y,Z for every node. Once you do that you're example will work. Examples of both (produced in ParaView via Data Object Generator (RG1 | SG1)->Write as XDMF) are attached. David E DeMarle Kitware, Inc.
