FinGreen3D

FINGREEN3D is an open-source package for computation of the free-surface Green's function under a finite water depth, which is the core-part of the boundary integral equations in the potential flow theory for analysis of wave-structure interactions. It is currently written in FORTRAN 90. The code is based on a state-of-the-art method developed in recent years by the authors. The main strategy of this method is to use a set of different series expansions in appropriate sub-regions. Therefore, we can avoid calculating the Green's function by direct time-consuming integrations.

FINGREEN3D is freely distributed under the LGPL License, Version 3.0, https://www.gnu.org/licenses/lgpl-3.0.html, and may be modified and extended by researchers who intend to enhance its capabilities and port the code to other platforms. The Mendeley release is the first(original) release of the FINGREEN3D package. The subsequent versions can be traced via its GitHub homepage: https://github.com/liuyingyi-ukyushu/FinGreen3D.

Tutorials are given inside the FinGreen3D package. Instructions for compiling and running the tutorial program, as well as calling the FinGreen3D dynamic-link library from a user program, is well introduced in the Readme.txt file.

FINGREEN3D is developed in the hope that it can contribute to the continuous development of offshore floating renewable energy systems as well as other ocean/marine engineering applications, regardless of academic or industrial purpose. Please cite the following associated paper in your relevant publications if the FINGREEN3D code or its executable (dynamic-link library) has contributed to your work:

FINGREEN3D是一款开源软件包，旨在计算有限水深下的自由表面格林函数，该函数是波动-结构相互作用势流理论中边界积分方程的核心部分。该软件目前采用FORTRAN 90语言编写。代码基于作者近年来开发的先进方法，其主要策略是在适当的子区域内使用一系列不同的级数展开。因此，我们可以通过避免直接耗时积分来计算格林函数。FINGREEN3D在LGPL许可证版本3.0下免费分发，网址为https://www.gnu.org/licenses/lgpl-3.0.html，研究人员可以在此基础上进行修改和扩展，以增强其功能或将代码移植到其他平台。Mendeley发布是FINGREEN3D软件包的首次（原始）发布。后续版本可以通过其GitHub主页追踪：https://github.com/liuyingyi-ukyushu/FinGreen3D。软件包内部提供了教程，Readme.txt文件中对编译和运行教程程序，以及从用户程序中调用FINGREEN3D动态链接库的说明进行了详细介绍。FINGREEN3D的开发旨在为离岸浮式可再生能源系统以及其他海洋/海事工程应用，无论学术还是工业目的，做出持续贡献。如FINGREEN3D代码或其实际运行（动态链接库）对您的工作有所贡献，请在相关出版物中引用以下相关论文：Yingyi Liu等. 《一种可靠的开放源代码软件包，用于评估沿海和离岸区域浮式可再生能源系统的性能》。《能源转换与管理》，2018年。》}
