[Paraview] best strategy for multi-block data?

[j s]

My data writer is already written.  It writes binary data to an
unstructured mesh file using zlib compression and base64 encoded data.
 It would not be very easy to rewrite it using the vtk libraries.  My
writers would be a lot easier to maintain with documentation of the
file format.

Regards,

Juan
