Karol Brzezinski proposed the following answer:
Hi Kasi,

next time please provide MWE (minimum working example) [1]. You provided
just one line of code, so no one can reproduce your problem without
additional assumptions.

However, I can guess that the problem is that you do not use the option
'distributeMass' [2]. Because of that, you do not distribute the mass of
the particles but the number. Thus your simulation is dominated by the
bigger particles, and it is likely the reason for the problem with
achieving the target porosity.

Best wishes, 
Karol
