Ewald summation, named after Paul Peter Ewald, is a method for computing long-range interactions (e.g. electrostatic interactions) in periodic systems. It was first developed as the method for calculating electrostatic energies of ionic crystals, and is now commonly used for calculating long-range interactions in computational chemistry.

The Ewald summation method used is described in pages 46-48 in the user manual which I unfortunately can't link because of my low ranking. I'm working with two papers which use the same computational methods. Again, I can't link anything but you can find the papers in arxiv.

Ewald summation program for computing the long range Coulomb interactions in 3D Periodic systems. Because the equation in Ewald summation program is complicated, it must be checked and verified. Here we do this by calculating the Madelung constant for the crystal structure of SiO2(beta-cristobalite) , TiO2(rutile), Al2O3 (corrundum) and ZnS(Sphalerite).

In the Ewald summation approach [ E WALD 21] the basic cell with containing each of positive and negative charges in some spatial arrangement is interpreted as a single crystallographic element surrounded by an infinite number of identical copies of itself. The entire system is then neutral and contains an infinite number of charges situated at The Ewald Breakup Method: Concept Idea: Break the potential into two pieces: † one short ranged in real space † one short ranged in k-space 0 2 4 6 8 10 0 0.5 1 1.5 2 2.5 3 3.5 4 4.5 5 r v short (r) Short range part of coulomb potential Long Range Potentialsand the Ewald Method – p. 12/24 1996-06-01 · 2. Ewald summation 2.1. Introduction Ewald summation was introduced in 1921 [23] as a technique to sum the long-range interactions between particles and all their infinite periodic images efficiently. For brevity, Ewald summation and Ewald sum will be used interchangeably. Ewald recast the potential energy of Eq. 3 The Ewald sum Ewald sum is a faster method to compute electrostatic quantities such as energies or forces.

Ewald summation rewrites the interaction potential as the sum of two terms where represents the short-range term that sums quickly in real space and represents the long-range term that sums quickly in Fourier space.
