Animate StreamTracer maximum length in conjunction with Extractor


Is there a way to animate the length of the StreamTracer so that as part of the Extractor output, it grows in length i.e. for every frame exported, the streamline grows longer?

Maybe some python snippet I can associate with Extractor to vary the length?

I am trying to illustrate the flow around objects and the length of the stream line helps me convey that message.


Is your dataset temporal ?

In any case, see this webinar:

Thank you @mwestphal , the webinar gave me more ideas to ponder.

I downloaded my dataset from an OpenFOAM simulation though it appears to have only a single time step in the data. I will now look for richer temporal dataset and apply the technique describe in the webinar.
