文摘

HOS-ocean is an efficient High-Order Spectral code developed to solve the deterministic propagation of nonlinear wavefields in open ocean. HOS-ocean is released as open-source, developed and distributed under the terms of GNU General Public License (GPLv3). Along with the source code, a documentation under wiki format is available which makes easy the compilation and execution of the source files. The code has been shown to be accurate and efficient.

Classification: 4.12.

External routines: FFTW 3.3.4 [1], LAPACK [2] and makedepf90 (linux.die.net/man/1/makedepf90)

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 N_x=1024$N_x=1024$ modes and an HOS order 5230e3c36a0cc98d1623e20a34" title="Click to view the MathML source">M=5$M=5$: $t\cong 2.010^{-1}s$ per wave period

3D simulation of irregular wavefield with N_x=256$N_x=256$, N_y=256$N_y=256$ modes, an HOS order M=3$M=3$: $t\cong 10s$ per wave period.
