We have estimated the RDFs between cavity and urea molecules in water-urea and water-urea-TMAO mixtures which is shown in Figure . The density of urea in the solvation shell of cavity is higher in water-urea-TMAO mixture in comparison to water-urea mixture for Garcia force field although the considerable increment is observed for Netz force field. In the case of Netz force field, a sharp peak is found which indicates more ordered structure of urea around cavity.
