I want to count two sizes of particles separately with fix massflow/mesh command. I thought it should be very straightforward but I didn't figure out how to do that.

Thanks and best regards,
Min

Hi, Min,
Have you solved this issuse? Could you please share the method which can count number of different type particle crossing a spefical plane? Many thanks!

i think you can apply the fix massflow/mesh command to different group-IDs, so if you make each particle size its own group, that should work

After running your simulation, you can perform post-processing connections analysis using LAMMPS output files (e.g., dump files) to count particles of different sizes separately.
