Dear lammps user,
I am simulating a liquid where very low concentration of water is present say 2% or 3% from literature we have found that the oxygen atoms under low water concentration forms a cluster and I want to determine the cluster size the distance between the atoms was found to be 3.5A . So after grouping the atoms properly I ran the command
Compute cluster oxygen cluster/atom 3.5
Dump calc_agg oxygen custom 100 cluster.dat c_cluster
but, nothing is there in the dump file.
