Can you share the data (or a small subset - maybe a 10x10-ish grid
with 1 field of value (the z coordinate) )? I can poke around with it
tomorrow. I'd probably write a little VTK program to simply convert
the field data into the actual z component of each point's coordinate
- maybe someone can tell you how to do this inside Paraview?

Thanks,

David
