Master's thesis presentation. Francisco is advised by Gerasimos Chourdakis.
SCCS Kolloquium
The SCCS Colloquium is a forum giving students, guests, and members of the chair the opportunity to present their research insights, results, and challenges. Do you need ideas for your thesis topic? Do you want to meet your potential supervisor? Do you want to discuss your research with a diverse group of researchers, rehearse your conference talk, or simply cheer for your colleagues? Then this is the right place for you (and you are also welcome to bring your friends along).

Francisco Javier Martínez Quiles: Mixed-dimensional flow coupling with preCICE
SCCS Colloquium |
Partitioned multiscale flow simulations offer a computationally efficient alternative to fully resolved models by combining reduced-dimensional solvers with higher-dimensional simulations only where necessary. However, such approaches are sensitive to interface assumptions and cross-section modeling, which can restrict their applicability beyond canonical circular pipe geometries and idealized parabolic profiles.
This thesis extends an existing preCICE-based axial geometric multiscale coupling framework that previously supported only 1D–3D coupling for circular cross sections with a parabolic velocity profile. The framework is generalized to enable 1D–2D and 2D–3D coupling and is further extended to support both circular and square cross sections with configurable uniform and parabolic profiles for spread and collect operations. Geometryaware interface mappings are introduced to ensure physically consistent data exchange across solver dimensionalities. The proposed extensions are implemented and evaluated on steady laminar flow benchmarks in circular pipes and square ducts, serving to verify cross-section handling and profile consistency across dimensions. In addition, the coupling framework is assessed using a transient water-hammer benchmark to examine wave propagation, pressure evolution, and stability under strongly unsteady conditions.
The results demonstrate that the extended coupling framework reliably preserves the global flow behaviour observed in monolithic reference solutions for both steady and transient cases, while clearly exposing the limits of accuracy imposed by interface modeling choices. Coupling-induced errors are shown to remain localized near the interfaces and do not lead to instability or uncontrolled error growth, but they can influence local pressure levels and velocity distributions. The framework enables consistent multiscale coupling across different solver dimensionalities, cross-section shapes, and profile assumptions, thereby broadening the applicability of partitioned multiscale pipe and duct simulations and providing a flexible interface treatment for future coupled 1D/2D/3D studies.

Contribute a talk
To register and schedule a talk, you should fill the form Colloquium Registration at least four weeks before the earliest preferred date, at the end of a semester typically even earlier reservation is necessary due to a very high influx of presentations. Keep in mind that we only have limited slots, so please plan your presentation early! In special cases, contact colloquium@mailsccs.in.tum.de.
Colloquium sessions are now on-campus. We have booked room MI 02.07.023 for WS25/26. You can either bring your own laptop or send us the slides as a PDF ahead of time. The projector only has an HDMI connection, so please bring your own adapters if necessary.
We invite students doing their Bachelor's or Master's thesis, as well as IDP, Guided Research, or similar projects at SCCS to give one 20min presentation to discuss their results and potential future work. The time for this is typically after submitting your final text. Check also with your study program regarding any requirements for a final presentation of your project work.
New: In regular times, we will now have slots for presenting early stage projects (talk time 2-10min). This is an optional opportunity for getting additional feedback early and there is no strict timeline.
Apart from students, we also welcome doctoral candidates and guests to present their projects.
During the colloquium, things usually go as follows:
- 10min before the colloquium starts, the speakers setup their equipment with the help of the moderator. The moderator currently is Ana Cukarska. Make sure to be using an easily identifiable name in the online session's waiting room.
- The colloquium starts with an introduction to the agenda and the moderator asks the speaker's advisor/host to put the talk into context.
- Your talk starts. The scheduled time for your talk is normally 20min with additional 5-10min for discussion.
- During the discussion session, the audience can ask questions, which are meant for clarification or for putting the talk into context. The audience can also ask questions in the chat.
- Congratulations! Your talk is over and it's now time to celebrate! Have you already tried the parabolic slides that bring you from the third floor to the Magistrale?
Do you remember a talk that made you feel very happy for attending? Do you also remember a talk that confused you? What made these two experiences different?
Here are a few things to check if you want to improve your presentation:
- What is the main idea that you want people to remember after your presentation? Do you make it crystal-clear? How quickly are you arriving to it?
- Which aspects of your work can you cover in the given time frame, with a reasonable pace and good depth?
- What can you leave out (but maybe have as back-up slides) to not confuse or overwhelm the audience?
- How are you investing the crucial first two minutes of your presentation?
- How much content do you have on your slides? Is all of it important? Will the audience know which part of a slide to look at? Will somebody from the last row be able to read the content? Will somebody with limited experience in your field have time to understand what is going on?
- Are the figures clear? Are you explaining the axes or any other features clearly?
In any case, make sure to start preparing your talk early enough so that you can potentially discuss it, rehearse it, and improve it.
