HOS-Ocean is a numerical model dedicated to the propagation of non-linear wave fields in open ocean with arbitrary constant depth. It is based on the High-Order Spectral (HOS) method which enables the simulation of highly non-linear wavefields. It has been developed at Ecole Centrale de Nantes for 10 years and is used in several research projects.
This wiki details the procedure to download and use HOS-ocean as well as the documentation of the current installation.
HOS-ocean is available to download as a single program to compile and execute. This is written in Fortran language.
Any publication or report using HOS-ocean have to refer to the corresponding publications

Download of latest release version is available here.
Developers are welcome to contribute, cloning is available from the main GitHub page for HOS-ocean: here.
Note that a Numerical Wave Tank based on the HOS method, namely HOS-NWT, is also available here.
It is dedicated to the generation and propagation of highly non-linear wave fields in wave basins. The proposed model reproduce all features of an ocean wave basin: directional wavemaker, reflective walls and absorbing beach.
