RichardsFoam3: A new version of RichardsFoam for continental surfaces hydrogeology modelling

RichardsFoam3 is an updated version of the OpenFOAM® solver RichardsFoam, previously presented in “An open source massively parallel solver for Richards equation: Mechanistic modelling of water fluxes at the watershed scale” by L. Orgogozo, N. Renon, C. Soulaine, F. Hénon, S.K. Tomer, D. Labat, O.S. Pokrovsky, M. Sekhar, R. Ababou, M. Quintard (Comput. Phys. Commun. 185 (2014) 3358-3371, https://doi.org/10.1016/j.cpc.2014.08.004), and in the new version announcement “RichardsFOAM2: a new version of RichardsFOAM devoted to the modelling of the vadose zone” by L. Orgogozo (Comput. Phys. Commun. 196 (2015) 619-620, https://doi.org/10.1016/j.cpc.2015.07.009). This new version includes improvements of memory handling and of on-the-fly control of computations, a better integration in the OpenFOAM® framework, simplifications of the coding of some expressions, as well as new advanced boundary conditions. All together these developments allow to enhance the ease of application of the code to continental surfaces hydrogeology modelling, its computational performances and its readability. The description of the elements contained in this release may be found in the readMe file. Please note that you may also find RichardsFoam3 on the hydrology page of the develop.openfoam.com interface: https://develop.openfoam.com/Community/hydrology/ The previous version of this program (AEUF_v2_0) may be found at https://doi.org/10.1016/j.cpc.2015.07.009.

RichardsFoam3是OpenFOAM®求解器RichardsFoam的更新版本。该求解器的初始版本最早发表于L. Orgogozo、N. Renon、C. Soulaine、F. Hénon、S.K. Tomer、D. Labat、O.S. Pokrovsky、M. Sekhar、R. Ababou、M. Quintard合著的"An open source massively parallel solver for Richards equation: Mechanistic modelling of water fluxes at the watershed scale"，刊载于《Computer Physics Communications》185卷（2014年），页码3358-3371，DOI：10.1016/j.cpc.2014.08.004；其首个更新版本RichardsFoAM2的发布公告则由L. Orgogozo撰写，题为"RichardsFOAM2: a new version of RichardsFOAM devoted to the modelling of the vadose zone"，刊载于《Computer Physics Communications》196卷（2015年），页码619-620，DOI：10.1016/j.cpc.2015.07.009。本次发布的RichardsFoam3版本优化了内存处理与计算实时控制功能，提升了与OpenFOAM®框架的集成度，简化了部分表达式的代码编写，并新增了多款高级边界条件。上述一系列升级有效提升了该代码在陆面水文地质建模中的应用便捷性、计算性能与代码可读性。本发布版本的组件详情可查阅自述文件（readMe）。请注意，用户亦可在develop.openfoam.com平台的水文板块获取RichardsFoam3：https://develop.openfoam.com/Community/hydrology/。该程序的旧版本（AEUF_v2_0）可通过以下链接获取：https://doi.org/10.1016/j.cpc.2015.07.009。
