In an analogous way electrostatic potentials can be calculated on grids.
leads to calculation of the electrostatic potential of electrons and
nuclei (and external constant electric fields and point charges if
In order to prevent the calculation of singularities at
the positions of nuclei, for gridpoints that are closer to a nucleus than
a.u. the charge of the respective nucleus is omitted in the
calculation of the electrostatic potential for these points.
