I am interested in the bead spring system. Could anyone teach me more about how to choose all those fene and lj parameters, especially Rho (or Rhostar).
What should I pay attention to. Based on the exampls of chain tool, the value for Rhostar is 0.8442 and 0.6261144.
the polymer system I am interested is kind of polyethylene system. Any papers addressing such kind of issue will also be helpful to me.
