[Paraview] Creating vectors using multiple files and Vector projections on a Slice

[Burlen Loring]

Hi Pradeep,

David gave you a great answer which illustrates ParaView's flexibility 
nicely. I would add that, for reasons of convenience, performance, and 
efficient memory use, your best bet is to find a parallel capable reader 
for your data format, or to tweak your output into one of the existing 
formats.

For example, the BOV reader in the SciberQuestToolKit plugin handles 
uniform and stretched cartesian meshes like you have and it expects 
vector components in separate files. There are some usage notes about 
this reader here: http://www.hpcvis.com/vis/sq-bov-reader.html If you 
try it feel free to ping me off list with any questions.

I believe XDMF could also read raw binary data (sans hdf5). Having not 
used this myself, I don't the details, and I couldn't give it a strong 
endorsement. However, it maybe worth looking into.
