lammps里面的pair_coeff設(shè)置問題
|
|
|
仔細(xì)看了mannual; 假設(shè)pair_style lj/cut 8.0 為什么 pair_coeff * * 1.0 1.0 2.5 還要這樣設(shè)置?lj不是只需要sigma、epislon兩個(gè)參數(shù)么?cutoff已經(jīng)設(shè)過、 這個(gè)2.5是什么意思? 同理,如果pair_style lj/cut/coul/cut 10.0 pair_coeff * * 這里是設(shè)置2個(gè)還是3個(gè)參數(shù)呢? 多謝!

根據(jù)手冊: The latter 2 coefficients are optional. If not specified, the global LJ and Coulombic cutoffs specified in the pair_style command are used. If only one cutoff is specified, it is used as the cutoff for both LJ and Coulombic interactions for this type pair. If both coefficients are specified, they are used as the LJ and Coulombic cutoffs for this type pair. You cannot specify 2 cutoffs for style lj/cut, since it has no Coulombic terms. 假設(shè)pair_style lj/cut 8.0 pair_coeff 1 1 1.0 1.0 2.5 這里的2.5就是type 1的原子和type 1的原子之間LJ勢的截?cái)喟霃,其余(例如type 2和type2 之間LJ勢)的截?cái)喟霃綖?.0. |
