[Paraview] Field value question from a user

[Moreland, Kenneth]

This is complex but can be done with the time support in VTK’s pipeline. However, it requires the filter to hold state from one call of RequestData to the next. This is simple enough in C++, but I’m not sure how you do it in the Python interpreter (used by the programmable filter). You could declare a global variable, but are you guaranteed to get the same interpreter instance each call? That’s a question for Utkarsh.

Greetings,

Is there a way with the calculator or something similar in paraview to grab the field value at a particular time step, so that I could then subtract it off of the time varying field?



Thanks,



Alan
