IMPORTANT INFORMATION:

Due to construction work Cologne Central Station (Köln Hauptbahnhof) will be closed between November 14th and 24th:

• Long-distance and regional trains will be rerouted or may be cancelled. Alternative stops include Köln Messe/Deutz and Köln-Ehrenfeld.

• S-Bahn services will largely continue to operate, with some exceptions during the nights of 18/19 and 19/20 November.

• Commuters can use stations such as Köln-Mülheim, -Deutz, -West, and -Süd, and transfer to the city’s KVB tram network.

Please check your travel plans in advance and stay up to date using the official websites.

This three-day event will provide a platform for insightful discussions, experience sharing among code users, and direct exchanges with the AC² development team. Additionally, GRS will present the latest improvements within the AC² code family, the upcoming release version AC2-2025, and outline the future development strategy.

We also encourage participants to contribute by presenting their recent applications, key insights, development needs, and ongoing or planned activities related to the AC² codes – ATHLET, ATHLET-CD, COCOSYS, and NuT.

A detailed agenda and more information will follow.
