A computer-simulation study of the equilibrium phase diagram of a three-dimensional system of particles with a repulsive-shoulder potential shows that at certain values of the potential parameters the system exhibits the waterlike thermodynamic anomalies: a density anomaly and a diffusion anomaly.

It is shown that the melting scenario drastically depends on the potential softness and changes with increasing the width of the smooth repulsive shoulder, which may be useful for the qualitative understanding of the behavior of water confined between two hydrophobic plates.

Several different forms of soft repulsion are considered, including a square shoulder, a linear ramp and a quasi-exponential tail, which may be the origin of unusual phase behaviors such as polyamorphism both in the equilibrium liquid phase and in the glassy state.
