Table summarizes results from MD simulations of dimethyl ether at a pressure of p = 50.0 bar , and methanol, and triglyme at p = 1 bar using orthorhombic unit cells with L z /L x = L z /L y ≈ 2.7933596497 for system sizes between 768 and 6144 molecules. The average densities of these systems are listed as averages over all system sizes in Table I. The true self-diffusion coefficients D 0 and shear viscosities η in addition to the system size dependent self-diffusion coefficients in z-direction D PBC,zz are reported for all three 0.04895 ± 0.00015 0.04667 ± 0.00008 systems and system sizes in Table . Here the viscosities are computed from the difference between D 0 and D PBC,zz according to Equation . Note that both the viscosity and D 0 do not indicate any systematic system size dependence. Table finally summarizes the self-diffusion coefficients and viscosities obtained as weighted averages over all systems. As indicated in Figure , the computed scaled differences between self-diffusion coefficients D 0 and self-diffusion coefficients in z-direction D PBC,zz show a linear dependence to the inverse box length in z-direction L z , in accordance with equation 9. Here the size of the relative error for D 0 obtained from individual simulation runs ranges from 0.3 % to 0.8 %, while the errors for D PBC,zz are smaller, and vary between 0.15 % to 0.5 %, whereas the relative uncertainty of the computed viscosity data shown in Table does not indicate any significant system size dependence and varies between 5 % and 7 %.
