I am a postdoctoral research in the group of Prof. M. Mehl at Stuttgart University at the Institute for Parallel and Distributed Systems (IPVS). Here I am member of the collaborative research center SFB1313 about “Interface-Driven Multi-Field Processes in Porous Media - Flow, Transport and Deformation”. My work within the SFB is concerned with efficient partitioned coupling schemes for porous media applications.
Before working in Stuttgart I obtained a master’s degree in Computational Engineering Science at RWTH Aachen University (Germany). After my master’s I started a PhD at RWTH Aachen University and Hasselt University (Belgium) where I was part of a joint PhD program. During my PhD studies I mainly focused on efficient high-order methods for computational fluid dynamics. I moved to the supercomputing center at KU Leuven where I worked as high-performance computing analyst/consultant for a year before going to Stuttgart.

We present recent results of coupling free and porous‐media flow applications and the development of the corresponding adapter. The main focus is on simulations based on DuMuX (https://dumux.org/) which is an open‐source framework for solving flow problems, especially porous‐media flow. We present results using the partitioned approach of preCICE for different scenarios and compare it, where applicable, with monolithic simulations or exact solutions.
Many real-world applications problems involve flow in porous media and some other medium that can be separated into subdomains by a sharp interface. An example is the flow of water (free flow) over a river bed (porous-medium flow). Modeling such an application involves different mathematical models in each of the subdomains and, thus, leads to ill-conditioned systems of equations when solved monolithically. Due to the ill-conditioning of the matrix, in the monolithic approach one has to use direct linear solvers or has to develop specialized preconditioners .
This poster is presented at the “Finite Volumes for Complex Applications IX” conference to be held online. It comes with a conference proceeding.
