Regarding repeated particles ID

Hello Mschramm,

As we discussed in the previous forum about particles repeated id, I found that particles id are repeated in my SIlo silulation.

I still didn't check the LIGGGHTS examples.

I converted all dump files in a csv file by using python. I tried to plot particles after 400000 or 500000 steps(rowsin csv) which is almost at the end of simulation. I was expecting all the particles will be on the floor but I found that some of the particles are still hanging on the top of the silo.

Is it because I didn't use delete atoms comand?

I have attached my plot here.

I hope I didn't miss anything in my simulation.
Thanks
