 Hi Simone
    I have been looking at how to do this also.  I do CFD and also would 
like to setup some startdard post processing in Paraview.
I do not yet have any good solution though. Perhaps a TCL script that 
calls the calculator tool with different equations?
Has anyone come up with a way to set this up?  If anyone has some TCL 
scripts that they use to do standard post processing could
you post some examples for us?


Thanks
