HOS-Ocean v2.1: Extensions of a nonlinear wave solver based on the High-Order Spectral method

In this work, we report a new version of the HOS-Ocean code which is an open-source solver for deterministic nonlinear ocean wave propagation. The numerical model makes use of the so-called High-Order Spectral method, which ensures high efficiency and accuracy. This new release includes i) additional physical features such as spatially varying current and bathymetry together with dedicated models to account for wave-breaking, and ii) numerical developments with parallelization of the code through MPI as well as a more user-friendly code (pre-built binaries available, and simplified building procedure and operation). HOS-Ocean v2.1 is released as open-source, available from GitLab, developed and distributed under the terms of GNU General Public License (GPLv3). Along with the source code, detailed documentation under Sphinx format is available.
