[Paraview] couple of issues related with co-processing ...

[Ufuk Utku Turuncoglu (BE)]

Thanks. I'll look at those scripts to generate similar data to the 
co-processing.  By the way, i had a problem in the calculator filter and 
it was not working in co-processing but again it might be related with 
the data representation. I'll try it again when i create the multiblock 
dataset.

Regards,
