1、我是使用Packmol搭建的体系:1082个CO2、10个MEA,真空。利用Sobtop产生两个分子的拓扑文件,把两个[ atomtypes ]内容剪切到了自己写的box.top里:
#include "amber03.ff/forcefield.itp"
[ atomtypes ]
; name at.num mass charge ptype sigma (nm) epsilon (kJ/mol)
CZ 6 12.010736 0.000000 A 3.399670E-01 3.598240E-01
NT 7 14.006703 0.000000 A 3.249999E-01 7.112800E-01
#include "CO2.itp"
#include "MEA.itp"
[ system ]
CO2+MEA
[ molecules ]
; Compound #mols
CO2 1082
MEA 10
[ atomtypes ]下只有两种原子类型是因为我把已经在力场里定义过的删除了。
2、对这个体系进行能量最小化就一直报错:

3、请问各位老师,前两个警告可不可以忽略,后一种错误解决方式是什么。
附上一些文件:
力场文件我没有做任何修改。
