There is currently a month-long online hackathon throughout August around that idea. The challenge is to take differentiable components that don't naturally fit together (using different languages, frameworks, or autodiff strategies) and compose them so gradients flow through the whole thing, then use that to solve a real design, inference, or training problem. Tracks cover inverse design, multi-physics coupling, hybrid ML + mechanistic models, differentiable inference/ UQ, and differentiable rendering.

The software provides methods for transient-equation coupling, communication, time interpolation, and data mapping. Several free and proprietary codes are currently coupled with preCICE, such as OpenFOAM, SU2, and deal.II. preCICE's API is available in all languages you need: C/C++, Python, Fortran, Matlab, Julia, and even Rust. An online hands-on training tailored to participants in the Americas time zones will take place October 5–9, 2026. The course is suitable for beginners. Sessions will run daily from 12–3 pm EDT (UTC-4) and will cover both the essential first steps with preCICE and selected advanced features. The program will also include invited presentations from users in the Americas, together with a general overview of recent preCICE developments and news.
