Counting number of particles

Please login with a confirmed email address before reporting spam

Hi,

How is it possible to count the number of particles which remained in the domain in the last moment of simulation?

Hope to hear your answers.
Thanks

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.
