[交流] 各位老师，有没有用fix smd 来求应力应变曲线的已有1人参与

各位老师，有没有用各位老师，有没有用fix smd 来求应力应变曲线的，我有几个问题想请教下：在LAMMPS manual如下这部分
This fix computes a vector list of 7 quantities, which can be accessed by various output commands. The quantities
in the vector are in this order: the x-, y-, and z-component of the pulling force, the total force in direction of the
pull, the equilibrium distance of the spring, the distance between the two reference points, and finally the
accumulated PMF (the sum of pulling forces times displacement
中的the equilibrium distance of the spring具体指什么来求应力应变曲线的，我有几个问题想请教下：在LAMMPS manual如下这部分
