Dear all,

I want to compute radial distribution function for four nanoparticles in simulation. but i can not set RDF command for this problem. how to compute RDF for this problem?

thanks a lot.

You’re going to have to be more specific than “but I can not set RDF command for this problem”. How exactly can you not define a compute RDF? What is the error message? What version of LAMMPS are you using?
