[Paraview] Xdmf format and the contour plot

[wide li]

Hi there,

I have a basic question about the contour and stream line plots in ParaView. 

When I load my Xdmf file to the ParaView, neither of the contour nor streamline filters does function. 

I wonder WHY it is so and HOW I can solve this problem. At the moment, I really have no clue at all. The ParaView (5.0.0-RC1) is compiled and installed on Mac (El Capitan). In ccmake, I switched on 

PARAVIEW_BUILD_QT_GUI                 ON                                           
PARAVIEW_ENABLE_CATALYST         ON                                           
PARAVIEW_ENABLE_FFMPEG            ON                                           
PARAVIEW_ENABLE_PYTHON            ON 
PARAVIEW_USE_MPI                           ON
VTK_USE_LARGE_DATA                      ON.


Chosen by ParaView itself, all Modules are not activated except, 

Module_vtkWrappingPythonCore     ON.


Thanks very much in advance.

Li


PS. Here is my Xdmf file:
