Lammps density/number

WebbYou need to calculate the number density by "fix ave/chunk density/number". Then multiply by the bin volume set by your " compute chunk/atom" command to get the number of atoms in each chunk. sadibuz • 1 yr. ago I tried to do that but it showed wrong output. I was trying to start the chunk from 25.1 A° and set up the chunk length at 3 A°.
