Lx, Ly/nm Lz/nm D0/10 -9 m 2 s -1 DPBC,zz/10 that the obtained system size independent self-diffusion coefficients are in perfect agreement with the experimental value of 2.3 × 10 -9 m 2 s -1 at 298.2 K. The computed viscosities shown in Table are estimated with a relative accuracy of about 5 % to 6 % for the individual simulations and about 2.1 %, when averaging over the systems, which is significantly better than the accuracy which is available via the integration over the stress-tensor auto-correlation function as reported by Tazi et al.
