[Paraview] Calculate with global data

[Cory Quammen]

Alan,

Not possible with the Calculator as far as I know.

With the Python Calculator, you can indeed *use* a global variable
defined in the field data of the data set with the expression:

inputs[0].FieldData['TMSTEP'][time_index]

Here, time_index is the timestep index, not the time value. The Python
Calculator does not let you store the result in a new global variable.

The Programmable Filter is the most flexible filter that lets you read
the global data and store a new result. At the moment, however, I
cannot recall how to obtain the current timestep in the programmable
filter.

Maybe someone else can chime in, or I'll get back to you on how to do
this with the Programmable Filter. It is definitely more involved than
the using the Python Calculator.

HTH,
Cory
