Dear All,

I have a question while using castep, so I post it.

In CASTEP, should I use the dipole correction option when performing calculations with electric field(Electronic tab More.. > potential tab)conditions given?

The system at this time is a surface with slabs or a situation where single molecules exist in PBC.

In this case, I am confused about whether it is correct to use dipole correction.

Any advice from anyone would be appreciated.

Thanks.
