两个附件一个是输入文件,一个是mtp势函数文件,为方便上传都改为txt文件。

这个是输入完出现的,然后就什么都没了。是因为我的输入文件有问题吗?求指导

虽然我和你做的领域不一样,代码也看不出来什么问题。但是你说既不报错也不出结果的问题我也遇到过,我只能从个人经验上分享一下我的原因:minimize消耗了一定的步数,导致后续分析没有跑够输出一次的步骤就结束了。我的处理方式是在能量最小化后添加一个 reset_timestep 0。你可以试试这样设置后有没有改变
# 能量最小化
min_style cg
minimize 1e-10 1e-10 5000 10000
reset_timestep 0
