- | Both programs give the same geometry and the same energy without cutoff. Both codes use different cutoff: while in Fireball only the contributions of rij<rcutoff are included in Riccardo's code are the contributions from rcutoff2>rij>rcutoff included with coefficient which changes from 1 (on rcutoff) to 0 (on rcutoff2) - it is fitted by polynom of the 5.th order. | + | Both programs give the same geometry and the same energy without cutoff.
