Web大家好，我是小马老师。本文介绍lammps in文件中使用混合键势的方法。在以前的推文中，介绍比较多的是混合对势的写法（pair_style hybrid),其实，在同一个模拟体系内，键 … WebDescription The harmonic/shift bond style is a shifted harmonic bond that uses the potential E = U min ( r 0 − r c) 2 [ ( r − r 0) 2 − ( r c − r 0) 2] where r 0 is the equilibrium bond distance, and r c the critical distance. The potential is − U min at r 0 and zero at r c. The spring constant is k = U min / [ 2 ( r 0 − r c) 2].

Since the hybrid keyword operates on pair style computations, it is mutually exclusive with either the pair or the inner / middle / outer keywords. WebA middle asterisk means all types from m to n (inclusive). Note that using a bond_coeff command can override a previous setting for the same bond type. For example, these commands set the coeffs for all bond types, then overwrite the coeffs for just bond type 2: bond_coeff * 100.0 1.2 bond_coeff 2 200.0 1.2.
