Prob in Particle Tracking_no. of positions
 

Dear all,
I want to know what is exactly mean by (A)Number of positions and (B)Mass flow rate in,
Boundary condition(inlet)>Fluid Values>

In CFX documentation it says input total no. of injecting particles for (A) if it is steady and if it is transient use no. of particles per unit time for (A).

If I want to introduce 15000 particles for a domain, within 10min, is it correct to use (A) as 25? {[15000/(10X60)]=25 particles per second}

Please consider my problem whether it is a very basic theory, as I think I understood this one wrongly.
