Time-average mass flow rate not same as provided?

There was an error rendering this rich post.

For EDEM simulation,
when I gave mass flow rate at the inlet say 1g/s and when I calculated at a region near the outlet, I am getting different average mass flow rate (delta m/delta t) at every time step. The time-average mass flow rate should be the same which I provided at the inlet. But I am not getting the same.

Hi, I'd recommend checking if the flow rate at the inlet is the same as what you have set. If there isn't enough space to generate the flow of material it will generate a lower flow rate.

This video outlines how to check the generation:

Yes, also the issue is average mass flow rate measured through at the outlet is observed less than expected. I am not sure about the reason. I took all exact particle-particle and particle-wall properties.
