Hi Daniel,
Many thanks for useful blog post. I chose the first approach and I found strange result.
In selection if I choose "Entire geometry" which means the whole domain [Am I right] entire geometry photo, then the number of particles are different from the one that I choose domain and the whole domain [I attached two screen shot].
Is there any reason for this result? 
More detail about my particle tracing module in my model: I released 100 particles and it seems that if I choose in selection "Entire Geometry" then this evaluation is not working correctly in COMSOL!
Hope to hear from you.
