Background

Note: I frequently use the easier (but unofficial) form of my name "Gerasimos" → "Gerasimakis" → "Makis".

Research interests

  • Multi-physics, black-box coupling
  • Geometric multi-scale modeling (1D-3D, 2D-3D coupling)
  • Fluid-fluid, multi-model coupling
  • Fluid-structure interaction (FSI), Conjugate heat transfer (CHT), Computational fluid dynamics (CFD)
  • Research software engineering, software sustainability, documentation, testing, continuous integration, fostering software communities

Research projects

  • Dissertation "Flexible Algorithms and Software for Complex Geometric Multi-Scale Coupling" (2018 - today)
  • Project ATHLET-preCICE, together with GRS (6/2019 - today)
  • Co-developer of preCICE, a free/open-source solver coupling library for multi-physics simulations with long history and users in several countries. As this project grows and targets users outside our research group, I am also interested in good software engineering practices, as part of the research project preDOM. (2017 - today)

Open and running student projects

If you are interested in a student project (Bachelor's or Master's Thesis or anything else), please contact me directly, with a few details on what you are interested in and describing your experience with simulations and related tools. I am mostly working with preCICE, for which you can also see our student projects with preCICE. See also the pages of my colleagues Benjamin Rodenberg, Frédéric Simonis, and Benjamin Uekermann, as well as the Student Projects at our chair.

I also frequently collaborate with Amine Abdelmoula (TUM Institute of Helicopter Technology). Contact him if you are looking for application-driven student projects involving fluid-structure interaction with preCICE. His colleague Sumeet Kumar is also working on FSI in helicopters and is often looking for students.

Do you want to know what other students are working on in our chair? You are warmly encouraged to attend their presentations at the SCCS Colloquium! Come to get ideas, meet your potential supervisor, or to learn from the style of others for your own presentation.

Open student projects

I do not currently have concrete project descriptions, but contact me if you enjoy developing simulation software, especially if you enjoyed CFD Lab or a similar course. Programming experience with OpenFOAM or other open-source solvers is highly relevant.

Do you like the general direction but you don't know what exactly you want to do? Contact me and we may find something fitting.

Running student projects

  • Markus Mühlhäußer is doing his Master's Thesis for M.Sc. CSE. The working title is "Partitioned flow simulations with OpenFOAM and preCICE". In this work, we are aiming for deeper understanding of fluid-fluid coupling, extending and improving the FF module of the OpenFOAM-preCICE adapter.
  • Tina Vladimirova is doing her Interdisciplinary Project for M.Sc. Informatics. The working title is "Design, implementation, and validation of a volume coupling extension for the OpenFOAM-preCICE adapter". In this work, we are aiming to extend and integrate community contributions for volume coupling to the OpenFOAM-preCICE adapter.
  • Elia Zonta is a student assistant contributing to the development of the geometric multiscale feature of preCICE.
