WebbThe particle-mesh Ewald (PME) method [37,38] was used to calculate long-range electrostatic interactions with grid spacing of 0.8 Å. Van der Waals (VDW) and short-range electrostatic interactions were smoothly truncated at 9.0 Å. ... Petersen, H.G. Accuracy and efficiency of the particle mesh Ewald method. J. Chem. Phys. 1995, 103. Webb31 aug. 1998 · The previously developed particle mesh Ewald method is reformulated in terms of efficient B ‐spline interpolation of the structure factors. This reformulation allows a natural extension of the method to potentials of the form 1/ rp with p ≥1. Furthermore, efficient calculation of the virial tensor follows.
