[Paraview] animating particle pathlines

[David I. Robinson]

Hello,

I’m trying to visualise lagrangian particle pathlines.  I have run an openFoam simulation with particle tracking and would like to view the paths that the particles take.  I have read lots of discussion of this on the internet, but without much success.  I can load the data in Paraview and assign glyphs, but I can’t visualise the pathlines taken by the particles.

I am cautious that Paraview might have some functionality for interpolating particle tracking from the eulerian data.  I might end-up visualising this approximation, rather than the lagrangian data calculated on a timestep-by-timestep basis by openFoam.  (Although an ability to do either or both would be useful!)

So far, my best luck seems to have come from masking my data and then using the particlepath filter, using the un-masked data as my input and the masked data as a seed.  This is OK, but requires me to incrementally increase the finished time to observe the particle paths.

Can you offer any help?
