One straightforward way is to realize such a function using a spiral phase plate [4,33]. Citations are the number of other articles citing this Our results for whole‐molecule van der Waals surface areas (vdWSAs) were 10 times more accurate in relative error, relative to actual hard‐sphere areas, than those reported by earlier workers. Free energy is an ensemble property, not a molecular property, so we are immediately faced with the need to make some approximations in order to render the modeling tractable. If your sample is dilute, increase nt to 8 or 16. The explicit model of the solvent provides the most rigorous solvation energy calculation [4]. An important challenge associated with adding explicit solvent molecules to implicit solvent calculations is that it is difficult to determine how many solvent molecules are required in order to reach convergence.
