Molecular dynamics simulations are used to study the properties of water modelled by the CF1 potential. The shifted-force CF1 model of water is introduced and studied. By shifting the force and potential curves in such a way as to remove the long-range Coulomb tail, it is possible to form short-range potentials which capture a few features of the actual CF1 potentials.
