[lammps-users] Issue with Tersoff potential

in T88:
b = (1 + Beta^n * zeta^n)^(-1/2n)

in T89
b = chi * (1 + Beta^n * zeta^n)^(-1/2n)

is ok but if u see the formula

V=fc®[fr®+bFa®], where Fa®= -Bexp^(-mur)

take the chi out and multiply it with B for a particular configuration.


Right, thanks, I should have noticed it.

BTW, do you have a potential file for SiC?
