This version supports multi-component systems with all parameters being dependent on the types of the atoms involved, i.e. the two-body terms dependent on the types of atoms i and j, whereas the three-body terms depend on the types of atoms i, j, and k. WebLAMMPS parameter values for Tersoff_2 can be obtained as follows: gamma = omega_ijk, lambda3 = 0 and the value of m has no effect. The parameters for species i and j can be calculated using the Tersoff_2 mixing rules: Tersoff_2 parameters R and S must be converted to the LAMMPS parameters R and D (R is different in both forms), using the … road trip games for teens printable pdf
