Hi all,


I'm enjoying some particle tracking with MPPICFoam, compiling it with foamToEnsight and visualizing it in salome/Paraview.



I'm doing everything I can, but there is no way to visualize a colored map of particule density, the only way is a monochrome particle cloud, which is not that useful.







My work is based on the glorious "injectionChannel" tutorial (if you never ran it, do it, it is really nice to look at).


Is there a trick I am missing ? How to extract and visualize a particles/cm³ 2D map ?

Do I have to write a dedicated script ?



Cheers,


A.

Hi Destouches, nice simulation. I also came across the same question, how to visualize the density of the particles, and my solution was:

1- Extract cloud position and save it in a .csv file (File -> Save Data)
2- Use a gaussian-KDE(Gaussian kernel density estimation), to visualize the cloud density https://python-graph-gallery.com/86-...th-2d-density/
