[Paraview] Xdmf format and the contour plot

[Tim Gallagher]

Apply a CellDataToPointData filter after you load your dataset and before you try to use the contour or stream line filters. They both require node-based data but you are providing cell-centered data.

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
