Reply To: Regarding pre filling a geometry before multiphase vof simulation

[Sumit_Kumar]

"At 0.1 micron and 0.01mm/s the particle isn't going to go anywhere other than by Brownian motion, diffusion or numerical errors: ie you won't see it move unless the fluid is also moving.", this does make sense.

But how do I calculate the momentum of injection and the relaxation time?
