HOS-ocean: Open-source solver for nonlinear waves in open ocean based on High-Order Spectral method

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.

Computer: Tested on Intel Xeon E5504 and Intel Core i7. Operating system: Any system with a Fortran compiler: tested on Linux, OS X and Windows 7. RAM: From several MB up to several GB, depending on problem (512 x 512, M = 3: 385 MB and 256 x 256, M = 3: 99 MB) Classification: 4.12. External routines: FFTW 3.3.4 [1], LAPACK [2] and malcedepf90 (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 modes and an HOS order M = 5: t congruent to 2.0 10(-1) s per wave period 3D simulation of irregular wavefield with N-x = 256, N-y = 256 modes, an HOS order M = 3: t congruent to 10 s per wave period.
