PCSS’ Patronage of the 30th SIMULIA Software Users Conference

PCSS’ Patronage of the 30th SIMULIA Software Users Conference

The event will be held in Poznań over three days: 21–23 October 2025. PCSS’ patronage is the result of a partnership and a testament to years of fruitful cooperation with the company TECHNIA. A highlight of the conference will be the presentation by Wojciech Stefaniak titled From global maps to local details: WICHER-M and the future of weather forecasting.

TECHNIA and PCSS have been connected through joint projects for over two decades, continuously supporting Polish science and industry in the field of advanced computational engineering.

The 30th Conference of SIMULIA Software Users will serve as a platform for the exchange of knowledge regarding the use of the specialist tools platform and a separate 3DEXPERIENCE platform; it will also find its crucial role in creating digital twins.

On Wednesday, 22 October 2025 (at 15:10 CET panel), the Advanced Visualization and Interaction Department of PCSS will present its work: WICHER-M: Model for High-Resolution Weather Prediction, which was distinguished with the Best Poster Award at this year’s edition of the ML in PL Conference.

The presentation Simulation at hand — From global maps to local details: WICHER-M and the future of weather forecasting shows how the combination of the foundational model Aurora with lightweight super-resolution modules can significantly improve weather forecast accuracy, while retaining computational efficiency. The model was trained using the ERA5-reanalysis data sets and WTK-US, which was produced with the use of the WRF model. WICHER-M operates directly in embedding space, which allows it to gradually increase the details of forecasts in a multiscale manner: from large atmospheric structures down to local phenomena. Thanks to that it is possible to achieve forecasts of a quality comparable to high-resolution numerical simulations but at much lower computational cost.

This is an example of how machine learning and modern physical modelling methods can collaborate to open a new chapter in atmospheric simulations and engineering applications.
