Imagine a full week of learning as much as possible about coupling simulations and having all the people you need to talk to in the same room. That’s exactly how a preCICE Workshop looks like!
This year, it was the first time that we co-organized it together with users - the HPC and the Fluid Mechanics groups of the Helmut Schmidt University of Hamburg. Many thanks to Prof. Philipp Neumann and Prof. Michael Breuer for hosting us, as well the local organizing team (Marie Rathmann, Hauke Preuß, Guillaume de Nayer).
This workshop was also the most attended on-site workshop we have had so far, and with the largest number of contributions. Just see the schedule: nuclear reactors, flow coupling, particles, ice sheet modelling, multi-scale structures, advanced Quasi-Newton methods, adaptive meshes, muscles, isogeometric analysis, fires, neural networks… a wide diversity of topics! This was also the best place to introduce our new HPC preCICE training module.
The highlight? A keynote talk by Prof. Daniel Bodony (University of Illinois Urbana-Champaign, USA) titled “Fluid-structure interactions in high-enthalpy flows” (related publications at AIAA conferences: e.g., 2022, 2024). Thank you for all the encouraging feedback!
These workshops are not only a venue to demonstrate new applications, but also a venue for establishing collaborations. Did you know that you can get your improved numerical methods integrated into preCICE? It might just take a few rounds of design discussions, as Prof. Philipp Birken (Lund University, Sweden) can attest (related publication: Int J Numer Methods Eng, 2025).
This year, a few participants also demonstrated the increasing applicability of preCICE on coupling particle codes – read more on the recent blog post titled Flexible mesh-particle coupling with preCICE. Prof. Anthony Thornton (University of Manchester, UK) demonstrated the vision of multi-physics and multi-scale simulations of granular material with preCICE, in the framework of the Open Network on DEM simulations.
As always, this workshop was more than talks: It included hands-on training, posters, discussion tables, user support sessions, and meaningful connections. Ah, and a dinner on a ship!
Every year, we aim to record all talks of the workshop and make them available to the everyone in the community, on our YouTube channel. Today, we are releasing the first four “announcements” talks: News on the core library (Frédéric Simonis), News on the ecosystem (Gerasimos Chourdakis), News on the standardization process (Jun.-Prof. Benjamin Uekermann), News on the automation tools (Felix Neubauer). All talks have been recorded, and new videos will be available every two weeks and will be announced on our new LinkedIn page.
As for the next workshop, it will take a bit longer to happen: We are aiming for spring 2027, as Benjamin announced during the closing talk. Don’t tell anyone yet, but it will most probably be outside Germany – let us know which weeks work for you. Stay tuned to find out first! 
Happy coupling,
the preCICE team
