Dear Paraview users,

I have a few questions regarding the capabilities of Paraview to output particle tracks and pathlines for non-lagrangian field data coming from OpenFoam simulations

Firs of all, Is it possible to do it? If so:

(1) Does anybody know how to do it?
(2) Is it possible to write the particle tracks to file (i.e. ascii) so that these files can be processed using more powerful plotting tools such as xmgrace o gnuplot?
(4) Is it possible to track one of the scalar fields, for instance Temperature, as the particle moves along the domain? In other words, Could I write T(x(t), t) to file using Paraview?

I know I am asking a lot of questions all at once, but any leads or suggestions as to how to go about doing this will be greatly appreciated.

Regards,

Josue MG

Greetings Josue,

Without knowing a specific tutorial case from OpenFOAM, I can only guess that you're looking for something like this: http://www.cfd-online.com/Forums/ope...tml#post283475 post #3 and keep reading...

Dear Bruno,
Thanks for your reply! I had seen the post you suggested before I decided to create a new thread - I was happy to see what 7Islands had done but whenever I tried reproducing his pipeline in Paraview, I encountered issues when adding the particletracer filter and/or particle pathlines.
A little bit of background as to why I am interested in particletracking: I ran a computation of flow over a heated sphere using reactingFoam and, as I mentioned on my post above, I'm interested in monitoring the temperature of massless particles (or parcels of fluid) as they travel through my domain so that I can plot their residence time and temperature evolution.
Any ideas/suggestions?

Hi,
Any progress on this? I am also trying to compute pathlines for an unsteady fluid flow simulation.
Thanks,
