TRANSIENCE at the Brightcon 2025 Hackathon in Grenoble!

On October 12 – 17, 2025, our colleague Dr. Jakob Dürrwächter from Potsdam Institute for Climate Impact Research (PIK) joined the Brichtcon Hackathon 2025—a dedicated conference series to open source tools and data—to give a short course and a presentation on Flexibe Open Dynamic Material Systems Model (flodym), an open-source library providing key functionality for building material flow analysis (MFA) models.

Built on the principles of ODYM, this new tool allows users to write cleaner, more adaptable code, minimising errors and easing future modifications. The library tightly integrates multi-dimensional dynamic stock models—handling inflows, outflows, and stock values over arbitrary time steps—with the overall MFA structure, achieving both conceptual clarity and computational efficiency.

Following this, on November 9-14, 2025, Jakob gave another one-week course on flodym at the Depart de Sentier Autumn School on MFA-LCA coupling. 

The course gathered 28 participants who studied how MFA concepts like material composition and the difference between stocks and flows can be applied to common LCA databases to check data quality, generate new inventories, and understand system effects outside of individual unit processes.
