Hi, I have simulated the flow thrrough a channel using pimpleFoam and I have added the particle tracking tool icoUncoupledKinematicCloud. In order to post process the results I need the position of the particles at each time step.

After the simulation, for each time step, a lagrangian folder is created, wich includes kinematicCloud properties in a folder. I think I can understand the output format of practically all the output files, except the position one. I expected to find the coordinates of each particle, or the control volume where each particle is located, but I am getting this output format for each particle.

(0.776997 0.172103 0.00169238 0.0492071) 176923 525202 1

If someone can help me to identify this output format I would be really gratefful.

Thank you for your attention and best regards.

Well, it's been some time since the code version of the OpenFoam foundation switched from cartesian coordinates to barycentric coordinates.

What I do is to open the lagrangian phase in paraview and then export to .csv which will give you the 3 coordinates. If you have lots of data you can create a python script to automatize this.

Please look at this thread and to this site

Hi again, I would like to ask another question related to the particle tracking tool. In the case of non-coupled particle-flow relation, how can i solve the particle tracking on a previously solved flow?
