Charge for a region

Hi,

Is there a way I can fix the charge for a region irrespective of number of atoms that are presently in the region? In short I want the region to have a fixed charge even if more atoms are added or some atoms are lost!

Thanks

I think you will have to manually reset the charges using the “set” command.

What is the physical motivation for this?

The easiest way would be to place one or more immobile charge particles in that region.
