Are you running under Windows or Linux? I have had many "large" vtk
data sets that crash ParaView on a Windows system because it cannot
allocate the memory. These same vtk data sets load correctly under
Linux. I was able to get a simple dataset based on your description to
load under Linux. The same dataset would not load in ParaView under
Windows. The reason that this occurs is the default windows version of
ParaView is 32-bit. 32-bit memory addressing under Windows is slightly
less than 2 GB. According to "top" on Linux, ParaView is running at
2GB. (FYI: My Windows machine is running Windows XP 64-bit and has 8
GB of RAM.)<br>
