[vtkusers] .vtu file format

[Scott A. Klasky]

Hi,
I am attempting to write out a .vtu file, and I can't seem to get ParaView
to read in the file. I'm assuming I'm doing something wrong, so please tell
me where the problem is.
 
The vtk file (which works) and the .vtu file (in ascii- which doesn't work)
are given below.  Please tell me where the mistake is.
 
I want to eventually write binary .pvtu files, but hopefully this will be
easy to write assuming I can write an ascii .vtu file first.
 
 
Regards,
 
 
Scott
