It depends on the method to treat electrostatic interactions in the
system. The manual is your best friend.
When you try to calculate DC you should understand that the state of
the theory of DC is not still perfect and it is not in any case easy
to reproduce the DC excellently. This depends not on the FF model but
on the way you estimate DC of the system.
