One of the most common applications of generalized force fields is to simulate organic solutes in an aqueous solution. A wide range of water models are available, including models with charges at the three atomic centers (e.g., TIP3P), models with an off-center charge (e.g., TIP4P), and polarizable water models (e.g., SWM4-NDP). The generalized force fields evaluated here are typically used with the TIP3P water model. The TIP3P model overestimates the dielectric constant and diffusivity of water,
