Hi,

I am modeling a spray injection and the injection lasts only for 20ms and the injected particles take 0.14s to traverse the flow domain, to make the simulation realistic as well as to reduce the computational cost(I will be tracking 5million particles instead of 1 lakh particles) I guess I would have to write a user subroutine for this since there is no readymade function for this sort of thing, if anyone has faced a similar sort of problem can they share their code or suggest any other method of achieving this sort of mass flow.
