[Paraview] error message

[Stephens, Michael M ERDC-ITL-MS]

karen,

here's a possibility.
i haven't done the math for your number of points/cells; but xml files have
an inherent size limit.
i've seen this error for appended vtk xml files (not ascii as yours are)

i believe it has to do with the size of the offsets.
it's a limitation of xml itself.

i've use vtkpython scripts on a 64 bit linux machine to write vtk xml files
that i can't read
with vtk or paraview. which is just wrong. 

i've asked that the xml writers take a look at what's being written
and at least send a warning that the file violates this xml limit.
hasn't happened yet.

just a thought.

Dear paraview developers and users,

I got this error when I attempted to open a .vtu file:

I guess it's all the same error. I  have some working files from before and I
created this file from the same script. I have checked the number of points
and the number of elements literally more than 5 or 6 times, and I have no
idea why it would give me ths kind of error... My file is huge so I won't
sent it, but it looks roughly like this:

<?xml version="1.0"?>
<VTKFile type="UnstructuredGrid">

... (number of data entries = number of nodes = 6225340)
</DataArray>
</PointData>
</Piece>
</UnstructuredGrid>
</VTKFile>

Could the problem be that the file is too large? I'm running on a Macpro with
16 GB's of RAM, and it's a 2 x 2.26GHz quad-core Intel Xeon processor.

Any help would be greatly appreciated!

Thanks,
Karen
