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。该原始求解器最早由L. Orgogozo、N. Renon、C. Soulaine、F. Hénon、S.K. Tomer、D. Labat、O.S. Pokrovsky、M. Sekhar、R. Ababou、M. Quintard于2014年发表于《Computer Physics Communications》第185卷（页码3358-3371）的论文"An open source massively parallel solver for Richards equation: Mechanistic modelling of water fluxes at the watershed scale"（DOI: 10.1016/j.cpc.2014.08.004）中发布，后续又在L. Orgogozo2015年发表于该期刊第196卷（页码619-620）的版本更新公告"RichardsFOAM2: a new version of RichardsFOAM devoted to the modelling of the vadose zone"（DOI: 10.1016/j.cpc.2015.07.009）中推出了RichardsFoam2版本。 本次新版本优化了内存管理与计算实时调控功能，提升了与OpenFOAM®框架的集成度，简化了部分表达式的编码逻辑，并新增了高级边界条件。上述一系列改进可有效提升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。 本次发布包所含内容的详细说明可查阅readMe文件。 请注意，用户亦可通过develop.openfoam.com平台的水文学板块获取RichardsFoam3，访问链接为：https://develop.openfoam.com/Community/hydrology/ 该程序的旧版本（AEUF_v2_0）可通过DOI: 10.1016/j.cpc.2015.07.009获取。
