WebThe in nite sum in Eq. (3) not only converges very slowly but also is conditionally convergent, meaning that the result depends on the order of the summation. The Ewald method evaluates Eby transforming it into summations that converges not only rapidly but also absolutely. The nal expression of energy in the Ewald method is given by Eq. (39). Web27 jun. 2015 · In this paper, derivations of the Ewald sums in the doubly and singly periodic cases are presented in a uniform framework based on Fourier analysis, which also yields a natural starting point for FFT-based fast summation methods.

Another way for improving the Ewald method is to perform fast Fourier transform (FFT) of a reciprocal space sum on a mesh. The oldest algorithm of this kind is the so-called Particle-Particle Particle-Mesh (P3M) method, invented by Hockney and Eastwood in the Web1 apr. 2024 · We have implemented the computation of Coulomb interactions in particle systems using the performance portable C++ framework Kokkos. For the computation of the electrostatic interactions in particle systems we used an Ewald summation. This implementation we consider as a basis for a performance portability study.
