Default Post: Particles Rate per Volume
Posts: n/a
Would anyone know how I would go about finding out how many particles have passage through a small volume of my domain over a specified time period? Is this possible? Do I have to create sub-domains?

The option "particle number rate" can not be activated for anything except "function calculator".

Also I've look in the manuals, but I can find a clean definite of what "particle volume fraction" mean in CFX-Post. When I plot this on a log scale I get 1 for where there are particles and 0 for where there are no particles passing through the domain.

Thank you!
