Webb25 maj 2001 · A particle mesh Ewald method for calculating Coulomb interactions in three-dimensional (3D) systems with two-dimensional (2D) periodicity was developed. Computational efficiency and accuracy of this method were evaluated for a TIP3P water system with 2928 particles in a cubic box with 2D periodicity. WebbThe Ewald method gives the exact result for the electrostatic energy of a periodic system consisting of an infinitely replicated neutral box of charged particles. The method is the natural choice in MD simulations of complex molecular system with PBC. The Ewald potential [ 33] is given by ( 4. 20) ( 4. 21) with ( 4. 22) ( 4. 23)
