DuMux is a free and open-source simulator for flow and transport processes in porous media, based on the Distributed and Unified Numerics Environment (DUNE). Its main intention is to provide a sustainable and consistent framework for the implementation and application of model concepts, constitutive relations, discretizations, and solvers. The paper provides an overview of DuMux with the focus on software-related aspects. Selected examples highlight the multi-scale and the parallel capabilities. 相似文献

Multi-phase flow and transport processes generally occur on different spatial and temporal scales. Very often also, within a physical system, they vary in space meaning that different kinds of processes might take place in different parts of the system. In order to account for the variety of processes and to take their scale-dependence into account, the development of multi-scale multi-physics techniques can be envisaged. 相似文献

A fully coupled multi-physics finite element model has been used to conduct a back-analysis of a stope filling case history at the Kanowna Belle (KB) mine in Western Australia. The model captures a number of important characteristics of mine backfill behaviour, including the evolution of strength and consolidation properties with cement hydration, the impact of chemical shrinkage (self-desiccation) and de-saturation. Material parameters for the constitutive model have been calibrated using published laboratory test data. A reasonable match between ideal and actual elements of response as revealed through in-situ measurements of total stress and pore pressure was obtained using these initial parameters. A parametric study was then performed which showed that the backfill strength parameters (friction angle, dilation and cohesion), the chemical volume shrinkage, the rate of cement hydration and the water retention properties all have a significant influence on the calculated states of stress within the stope. 相似文献
