Is it possible to simulate a polydisperse system of disks in lammps in 2d? The problem is if I pour the particles I might not get a 2d packing.

Is it possible to simulate a polydisperse system of disks in lammps in 2d?

certainly.

The problem is if I pour the particles I might not get a 2d packing.

you will have to elaborate on this since 1) there is no requirement to use

fix pour for simulating a polydisperse system and 2) fix pour is 2d-aware,

so i don't see why this should not work.

Thank you for your reply. I thought that since I set the z direction periodic for -0.5 to +0.5 and I poured the particles from top with range lets say 0.7 to 1.0, the centers might not be fixed at z=0. I ran a sample simulation and all of them were coming at z=0. So my problem is sorted.

Thanks!

so where is the apology for asking a superfluous (and confusing) question?
