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. The Ewald sum is based on splitting the slowly convergent equation 1 into two series which can be computed much faster (at level of accuracy x ed). The trick basically consist on splitting the interaction 1=ras 1 r = f(r) r ¡ 1¡f(r) r (5) Ewald summation. Ewald summation is a method for computing long-range interactions in periodic systems [ Ewald1921 ]. In Metalwalls it is used for the Coulomb potential as well as the charge-dipole and the dipole-dipole interactions. The Coulomb potential involves point charges and Gaussian charges as described here.

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.

12/24 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 Ewald summation was first introduced as a method to calculate long-range interactions of the periodic images in crystals 105. The idea is to convert the single slowly-converging sum (1) into two quickly-converging terms and a constant term: If you find our videos helpful you can support us by buying something from amazon.https://www.amazon.com/?tag=wiki-audio-20Ewald summationEwald summation, na 3 The Ewald sum Ewald sum is a faster method to compute electrostatic quantities such as energies or forces.

The Ewald summation method[55, 56, 57] is a technique for evaluating the potential, subject to periodic boundary conditions, due to a lattice of point charges, plus a screening background, where is the position of the n charge in the simulation cell and is the set of supercell translation vectors. Ewald summation, named after Paul Peter Ewald, is a method for computing long-range interactions (e.g., Coulombic 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. Ewald summation is a special case of the Poisson summation 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.
