[vtkusers] Problem writing .vtu file : error with paraview reader

[François Rongère]

Hello,

I have some problem writing a .vtu file in XML format. It does not open 
in Paraview and the error message is :

ERROR: In /build/buildd/paraview-3.14.1/VTK/Filtering/vtkExecutive.cxx, 
line 756

vtkPVCompositeDataPipeline (0x220ce50): Algorithm 
vtkXMLUnstructuredGridReader(0x2212ab0) returned failure for request: 
vtkInformation (0x1065580)

Debug: Off

Modified Time: 71455

Reference Count: 1

Registered Events: (none)

Request: REQUEST_INFORMATION

ALGORITHM_AFTER_FORWARD: 1

FORWARD_DIRECTION: 0


Although I have searched and found similar issues in the archives of the 
mailing, I can't manage to find out what I am doing wrong.

I only want to store point location informations as well as cell 
connectivities to visualize unstructured mesh made of triangles and 
quads in paraview.  Does anyone could have a look at my problem ?

Here is the headers of my file :

I could also send the entire file for testing purpose.

Best wishes !
François.
