[Paraview] 32b vs 64b and Binary vs Ascii

[Michael Jackson]

What code are you using to write the .vtu files? Is it vtk code or is  
it code that you wrote for your own simulation? It sounds like it  
_might_ be incorrect values in the header parts of the velocity field.  
I believe .vtu files are ascii so you should be able to hand check the  
values that are being saved into the file with what you think you  
should be writing.

    Also on the off chance that your simulation is using either  
threads or MPI or something where it is distributed are you locking  
the section of code where the writing is performed? Possibly sounds  
like 2 processes maybe accessing and writing to the areas of memory as  
the same ares is being written to disk.

  Just some thoughts.
