From Lighthouse Cases to Exascale Practice: Outcomes of CEEC
Since 2023, the Center of Excellence in Exascale CFD (CEEC) has worked to make high-fidelity CFD ready for Europe’s exascale systems. Its work has been driven by six lighthouse cases, addressing challenges from aeronautics, offshore energy, process engineering, shipping, and atmospheric flows, chosen to push physics and software to their limits. This community workshop presents…

Localized Erosion of an Offshore Wind-Turbine Foundation
Uncertainty in suction bucket installation can increase the risk of localized soil erosion and foundation failure, with potential consequences for installation time and offshore wind project costs. Using HPC-powered, grain-scale fluid–soil simulations, CEEC improved the accuracy of engineering models for predicting erosion and suction behaviour, helping reduce installation uncertainty and support more cost-efficient foundation installation.…

Calibration of Analytical Suction Bucket Installation Models Using Grain-Scale LBM-DEM Simulations
Suction bucket foundations offer significant advantages for offshore wind applications, enabling fast and cost-efficient installation. However, installation failures due to piping erosion remain a critical challenge, particularly in loose or highly permeable seabeds. Understanding the interplay between seepage flow, soil properties, and foundation geometry during suction installation is essential for improving design guidelines and installation…

Advancing European HPC: Lessons from Porting Scientific Codes to RISC-V
On April 29, CEEC hosted our latest webinar exploring a key question for Europe’s digital future: how ready are our scientific applications for emerging European hardware? As efforts around European chip sovereignty accelerate, porting and evaluating applications on new architectures is becoming essential. In this session, CEEC experts shared hands-on experience working with long-vector RISC-V…

Exploring CI/CD Tools and Workflows for Research and HPC Software Projects
Continuous Integration and Continuous Deployment (CI/CD) are essential for sustainable and reproducible software development. This webinar provides a beginner-friendly introduction to CI/CD with a focus on the EuroHPC community. We will explore why CI/CD matters, review a selection of tools commonly used or even developed within European projects, and discuss their strengths, limitations, and typical…

CEEC at EuroHPCSummit2025
We ahad the pleasure of joining over 30 other EuroHPC Joint Undertaking funded projects developing skills, codes, technologies, and even international cooperation in the poster showcase at last week’s #EuroHPCSummit2025 in Krakow, Poland. As we enter the second half of our project runtime, we chose to showcase the scaling results of our codes so far.…
