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.

本研究中，我们发布了HOS-Ocean代码的新版本，该代码是一款用于确定性非线性海浪传播的开源求解器。该数值模型采用了所谓的高阶谱方法（High-Order Spectral method），可兼顾极高的计算效率与求解精度。本次新版本更新包含两方面内容：其一，新增了多项物理建模功能，例如空间变化流场与海底地形，并配备了专门的波浪破碎模拟模型；其二，完成了数值算法优化：通过消息传递接口（MPI）实现代码并行化，同时大幅优化了代码的易用性——提供预编译二进制文件，并简化了编译流程与操作步骤。HOS-Ocean v2.1以开源形式发布，可从GitLab获取，其开发与分发遵循GNU通用公共许可证（GPLv3）条款。除源代码外，该项目还提供采用Sphinx格式编写的详细文档。
