On the implementation of the shallow water model based on the quasi-gasdynamic approach in the open-source software package OpenFOAM

This paper presents RSWEFoam – a new solver for shallow water flow simulation, which is implemented based on the OpenFOAM v2012 open integrable platform using the finite volume method. The model of regularized shallow water equations underlying the solver is described, as well as the features of its implementation. RSWEFoam is integrated into an open-source framework QGDSolver for fluid and gas dynamics problems modeling within the QGD/QGD approach. The results of numerical simulation using a solver are presented.
