Hello everyone!


I'm currently trying to track particle using the solver icoUncoupledKinematicParcelFoam of OpenFoam 7.

My simulation runs well but the only positions for the particles that I get are barycentric coordinates. And I didn't find on Internet an easy method to switch barycentric coordinates to cartesian's ones...


So I tried to do it using Paraview by using this method:



1) run the simulation
2) type paraFoam on the terminal

3) add the filter extrudeBlocks and chose lagrangian data
4) open a new layout and select spreedsheet view
5) export date into .csv file


I was really happy with this method when I figured out there was a problem. Indeed, if, for exemple, in the file time1.csv, at the line 3 there is the coordinate of the particle 3 then in the file time2.csv, at the line 3 it's not the coordinate of the particle 3 anymore but of another one...



It's really a problem for me because I need to follow the trajectory of the particles...



I was wondering if there is a way in Paraview to print the trajectory of particles?

Thanks to all in advance, hope someone know how to do that...
