Reply To: How to know the mass flow rate at outlet surface when using DPM model?

If you've not used "scale by area" on the injection it's not a bad idea as all parcels will be the same mass. Equally, if that is the case, particles (parcels) injected is what goes in, and particles (parcels) escaped is what leaves - do you want the mass or fraction of mass on the outlet?
