  • Research software engineering, software sustainability

Student Projects

Open student projects

Topics change with my ongoing work and depend mostly on the interests and experience of the student. It is best to contact me directly if you are interested in a thesis or student project. Here is a list of topics I am interested in:

Running Student Projects

  • Armin Ettenhofer is writing Master's thesis on a coupled atmosphere-ocean model with preCICE
  • Niklas Vinnitchenko is working on improvments for the MATLAB bindings of preCICE and develops and maintains tutorials

Past student projects

  • Tobias Eppacher implemented parallel-in-time methods using pySDC in the partitioned heat equation with FEniCS and preCICE.
  • Marc Amorós Trepat did convergence studies for higher-order time stepping schemes of OpenFOAM, CalculiX, and a coupled simulation of OpenFOAM + CalculiX.
  • Niklas Vinnitchenko developed a tutorial for higher-order coupling of the partitioned heat equation with FEniCS and preCICE.
  • Nikola Wullenweber worked on automated quality analysis of black-box models for her IDP (interdisciplinary project).
  • Hisham Saeed developed a first prototype and corresponding test scenarios for the Elmer adapter for preCICE during his master thesis.
  • Nikola Wullenweber worked on solving different problems in FEniCS using higher-order time stepping schemes for her bachelor thesis.
  • Ishaan Desai worked on the FEniCS adapter and the Fluent adapter for preCICE and its python bindings.
  • Moritz Gnisia was a student assistant. He modernized the code framework of the course "CFD Lab" and developed a CI infrastructure and auxiliary tools for the course.
  • Richard Hertrich developed a tutorial for the "replay mode" of preCICE as a student assistant.
  • Richard Hertrich developed FSI tutorials for preCICE that use FEniCS and OpenFOAM and extended the FEniCS adapter for preCICE during his bachelor thesis.
  • Richard Hertrich also worked on the Fluent adapter for preCICE during his research internship.
  • Dominik Volland developed the MATLAB bindings for preCICE during his master thesis.
  • Gilberto Lem Carrillo helped with the integration of the MATLAB bindings as a student assistant.
