The method combines the framework of the Spectral Ewald method for periodic problems (Lindbo and Tornberg in J Comput Phys 229(23):8994–9010, 2010.

In the Ewald summation technique, the central simulation box is infinitely replicated in all direc-tions, and the long-range forces are included by eval-uating the interaction of all molecules in the central box with all their images in the replicas. The Ewald An Exact Ewald Summation Method in Theory and Practice. / Stenberg, S.; Stenqvist, B. In: The Journal of Physical Chemistry Part A: Molecules, Spectroscopy, Kinetics 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) , … Ewald Sum .

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) the Ewald sum parameters on the computed dielec-tric constant and compare the orientational struc-ture of the liquid calculated from simulations with the Ewald sum to corresponding results from reac-tion field simulations.

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.

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.
