Hello,
As reported here
https://www.cfdem.com/forums/different-particle-size-distribution-betwee...
It seems that LIGGGHTS is not able to insert the required mass of spherical particles when specifying a particle distribution using
particledistribution/discrete/numberbased
Comparing the particle distribution expected with the one in the output file it is possible to notice an important shift in the mean value.
Moreover LIGGGHTS seems to insert much more mass than the one required.
Best regards
Matteo
