[交流] [讨论]MS的中Modify菜单中有Charge editing

MS的中Modify菜单中有Charge editing选项

该选项是否是编辑原子电荷的,是否可以研究不同电荷的离子掺杂问题。我用该选项研究MgO,其中Mg的电荷改为多少都可以,但几何优化的结果一点变化都没有,好象该选项没有起作用。不知为什么?我看了帮助(在下面),搞不懂原因,大家共同讨论,共同进步。请高手指导


Charge editing
The charge editing options on the Atomic Charges tab can be used to modify the charges on selected atoms.

Total charge: Displays the total charge on all selected atoms (or on the entire system if no atoms are selected).

Set all charges to: When selected, indicates that the charge on each selected atom will be set to the specified value.

Set total charge to: When selected, indicates that a calculated fixed charge will be added to each selected atom such that the total charge on all selected atoms equals the specified value.

Scale charges by: When selected, indicates that the charge on each selected atom will be multiplied by the specified value.

Average all charges: When selected, indicates that the charge on each selected atom will be set to the arithmetic mean of the charges on all the selected atoms.

Assign: Makes the specified changes to the charges on the selected atoms.
