Abstract

A modified 3D-Ewald summation is presented for accurately simulating the ion-dipole mixture under dielectric confinement. The method is based on the combination of image charges and image dipoles with the conventional Ewald summation and has a scaling O(^3/2). The accuracy and efficiency of our algorithm are examined through numerical examples.
