Waves is a C++ program to simulate an interface whose energetics are governed by the capillary wave hamiltonian.

[ H[h(x,y)] = \int_{x,y} \frac{\gamma}{2} \left| \nabla h(x,y) \right|^{2} ]

where \gamma is the surface tension of water. Further details of this interface model are presented in the Supporting Information section of [Patel et al., Proc. Natl. Acad. Sci. USA, 108, 17678-17683 (2011)] (http://dx.doi.org/10.1073/pnas.1110703108). The code also allows for addition external potentials to the hamiltonian to model the liquid-vapor like interface near hydrophobic surfaces.
