Bernd Flemisch (Universit\u00e4t Stuttgart): <\/strong>The open-source simulator DuMux – experiences and practices from 15 years of development<\/p>\n\n\n\n

DuMux is a free and open-source simulator for flow and transport processes in and around porous media written in C++. Its main intention is to provide a sustainable and consistent framework for the implementation and application of porous media model concepts and constitutive relations.
To this day, 25 versions of DuMux have been released with contributions by over 70 people, mainly located at but not restricted to the Department of Hydromechanics and Modelling of Hydrosystems at the University of Stuttgart. In this talk, we want to give an overview of the organizational aspects of DuMux: the development and maintenance process, software quality assurance, documentation, tutorials and the integration of new developers.<\/p>\n\n\n\n

Powei Huang (Eidgen\u00f6ssische Technische Hochschule Z\u00fcrich): <\/strong>Reactive transport modeling in aqueous environments using the Nernst-Planck formulation<\/p>\n\n\n\n

In this seminar, we discuss the validity of applying the Nernst-Planck (NP) equation to model the transport of ionic species. We compare the simulation results of the NP model to the commonly used single-diffusivity model and benchmark the NP model with reaction-driven flow experiments. Our results show that the NP model is relevant for modeling reactive transport processes with an intricate interplay between diffusion, reaction, electromigration, and density-driven convection.<\/p>\n\n\n\t
