我做的是激光烧蚀聚酰亚胺，CHON四种元素的含苯环聚合物，涉及化学键的断裂和重组。
各位大佬，帮我看看吧！求求啦！

按照官网文件的是 ERROR on proc 0: CHON-2019.ff:47: This force field file requires using 'lgvdw yes'
改了之后是ERROR: Non-existent ReaxFF type (src/REAXFF/pair_reaxff.cpp:310)

不知道你说的按照官网文件是什么意思。
但看上去显然

复制代码

这里多了一行，仔细阅读2L给你发的网站，弄清楚力场文件的格式，调整对就不会报错。

好的，感谢大佬，感谢感谢
是的，这个多了一个换行，正常是4行。其实我这个力场第一行就报错了，正常不应该啊。

他说是不正确浮点数ERROR on proc 0: Not a valid integer number: '50.0000'

会不会是其它地方的问题，模型或者in函数里的

好的，感谢大佬，感谢感谢
是的，这个多了一个换行，正常是4行。其实我这个力场第一行就报错了，正常不 ...

应该是文件第一行会有一行注释，见：

The force field file begins with a description line that, in turn, may optionally begin with a list of keywords between square brackets, for example (for an ACKS2+eReaxff force-field):

如依然有奇怪问题，可去LAMMPS社区求助开发者，https://matsci.org/，以我经历开发者回复很快并且相当到位。

楼主，最后是怎样解决这个问题的？

力场文件格式不对，要用右键PDF，复链接并打开。

没太听明白。具体哪里格式不对，右键PDF，复链接并打开？望不吝赐教

你的力场实在网上文献中下载的吧？保存过程中格式错了。
