Nature of problem:
HOS-ocean has been developed to study the propagation of highly nonlinear sea-states over large domains and long duration.

Solution method:
HOS-ocean is an implementation of the High-Order Spectral method, which solves the problem formulated on the free surface by means of a pseudo-spectral method.

Restrictions:
HOS-ocean is dedicated to the propagation of wave fields in infinite and finite constant depth, the evolution over variable bathymetry is not treated. Furthermore, simulations are restricted to non-breaking waves.

Running time:
2D simulation of irregular wavefield with Nx = 1024 modes and an HOS order
M = 5: t ≅ 2.0 10-1 s per wave period
3D simulation of irregular wavefield with Nx = 256, Ny = 256 modes, an HOS order M = 3: t ≅ 10 s per wave period.
