| Title: | Implementation of a multiphase Lattice Boltzmann Method for the simulation of water retention behaviour of CT scanned granular media | Language: | English | Authors: | Milatz, Marius  |
Keywords: | Unsaturated granular soils; Water retention behaviour; Multiphase Lattice Boltzmann Method (LBM) | Issue Date: | 7-Jun-2022 | Abstract (english): | This data set contains a multiphase Lattice Boltzmann implementation (C++ code) for the simulation of water retention behaviour in granular media and related example files to run a simulation of cyclic drainage and imbibition in a cubic computational domain that is derived from binarised CT data including spatial information of the solid and pore distribution. |
