WCCM 2026: abstract deadline
The World Congress on Computational Mechanics (WCCM 2026) will take place in Munich, Germany, on July 19–24, 2026.
We are again organizing a preCICE minisymposium: Multi-Physics and Multi-Scale Simulations With The Coupling Library preCICE (MS070)
The abstract deadline (already extended) is February 9, 2026.

preCICE Workshop 2027 in Delft
The 7th preCICE Workshop will be held for the first time outside Germany at Delft University of Technology, The Netherlands, on March 1–5, 2027. It is co-organized by Matthias Möller and his team from the Numerical Analysis group and the G+Smo community.
As in previous editions, the workshop will include user and developer talks, hands-on training sessions, discussions with the developers about applications and use cases, and ample opportunities for networking. A special focus will be on coupling to solvers based on Isogeometric Analysis (IGA).

Mesh–particle coupling
Mesh–particle coupling has been a recent development focus, building on preCICE’s just-in-time data mapping capabilities.
Robin Walloner summarized his bachelor’s thesis on coupling LIGGGHTS and OpenFOAM in a blog post: Flexible mesh‑particle coupling with preCICE
In parallel, David Schneider developed a coupling with MercuryDPM in collaboration with Thomas Weinhardt (University of Twente) and Anthony Thornton (now University of Manchester):
A dedicated publication covering these developments is planned.
New releases: v3.3.0 and v3.3.1
With preCICE v3.3.0, the focus was on improving clarity, portability, and tooling. The release introduces clearer coupling-state output, more informative error messages, and a substantially reworked tooling ecosystem, now bundled in the new preCICE CLI. Platform support has been extended, in particular for Windows via MSYS2.
Release highlights: Highlights of the new preCICE release v3.3
Since then, the bugfix release v3.3.1 has been published: Release v3.3.1 · precice/precice · GitHub
The next feature release, v3.4.0, is planned for April. The current milestone: GitHub · Where software is built
New preprint: waveform iteration
We published a new preprint titled A waveform iteration implementation for black-box multi-rate higher-order coupling. It provides a concise summary of the dissertation of Benjamin Rodenberg.
The paper describes how waveform iteration was integrated into preCICE and how the extension interacts with existing features such as data mapping, quasi-Newton acceleration, and parallel peer-to-peer communication. Design decisions are discussed in detail. Numerical results demonstrate significant error reductions—often by orders of magnitude—for the partitioned oscillator, partitioned heat, and perpendicular flap tutorials, even for extreme time-step ratios of up to 100:1 and 1000:1.
New preprint: data mapping for an ESM benchmark
Evaluation of preCICE (version 3.3.0) in an Earth System Model Regridding Benchmark: EGUsphere - Evaluation of preCICE (version 3.3.0) in an Earth System Model Regridding Benchmark
In Earth System Modeling, meshes of different model components usually do not match, requiring robust data mapping algorithms in coupling software. Building on the benchmark introduced by Valcke et al. (2022), this study evaluates preCICE and compares its results to those of specialized ESM couplers. While preCICE does not provide ESM-specific functionality out of the box, the study shows that, with appropriate pre- and postprocessing, it achieves comparable results. In particular, the use of radial basis function mapping yields significantly lower errors.
