Berk and Kent,
Thanks for the quick response,

The data is unstructured and written one file/processor.
file001.vtk
file002.vtk
...
file128.vtk (total processors = 128)

The total x,y,z field contains 128 blocks (or domains).
1-Can I put the list of the vtk files into a list_meta.vtk file and load
only the  list_meta.vtk file?

2-If I use say 32 processors for the visualization, do all 32 processors
read simultaneously (processor 1 reads file001.vtk, processor 2 reads
file002.vtk ... etc)? or does one processor read all files?

I should say that I am using ParaView version 1.6.2.
Stephen
