Inputting particle per second

Is there a way to get MFIX to input 1 particle every second into the model?
I have currently been doing this by mass flow rate but it seems to work for the first second and then input 2/3 particles in each second onwards

Hi -

Can you share your model? I’d like to take a look at the mass inflow. “Submit bug report” from main menu will create a zipfile you can post here.

Thanks,
