RichardsFoam2: A new version of RichardsFoam devoted to the modelling of the vadose zone
Description
Abstract RichardsFoam2 is an updated version of the OpenFOAM^®solver RichardsFoam, presented in Orgogozo et al., Comput. Phys. Commun. 2014. The new features are the following: (i) The direct handling of fully heterogeneous porous media, with all the van Genuchten parameters defined as spatially varying scalar fields. (ii) The computation of the density of water flux at each face of the mesh cells, which allows the implementation of fixed water flux (e.g.: rain flux) boundary conditions. (iii) The i... Title of program: RichardsFoam2 Catalogue Id: AEUF_v2_0 Nature of problem This software solves the non-linear three-dimensional transient Richards equation, which is a very popular model for water transfer in variably saturated porous media (e.g.: soils). It is designed to take advantage of the massively parallel computing performance of OpenFOAM®. The goal is to be able to model natural hydrosystems on large temporal and spatial scales.
