LES-Modelling of offshore wind farms using a high order continuous spectral element solver
In the last ERCOFTAC – Recent Advances in Turbulent Wind-Farm Dynamics event (22nd – 24th April 2026, Imperial College London, United Kingdom),
Herbert Owen presented a study about LES-Modelling of offshore wind farms using a high order continuous spectral element solver.
This study develops a high-fidelity Large Eddy Simulation (LES) framework to model offshore wind farms under the influence of gravity waves, which significantly affect wind flow and power output.
It employs a high-order spectral element solver (SOD2D) optimized for GPU computing to handle very large computational domains.
Advanced numerical techniques, mesh optimization, and actuator disk modeling are used to ensure accuracy and efficiency.
The approach is validated against reference data and applied to a real wind farm, successfully capturing flow dynamics and production patterns.
EoCoE is a European Horizon 2020 funded project of Centre of Excellence in computing applications. It is designed to enhance numerical simulation efficiency in the international context of the High Performance Computing (HPC) challenges. It focusses its application scope towards low carbon energy domains.
To measure solar energy's profound impact, we must contemplate the “carbon footprint” — a metric that quantifies the total greenhouse gas emissions caused by an individual, organization, event, or product. Traditional electricity production contributes heavily to a nation's footprint, with fossil fuels being the predominant energy source. By harnessing solar energy, we offset these emissions and aid in the progressive decline of our collective carbon footprint.
Switching to solar is more than energy change it's a commitment to a future with reduced carbon emissions

Our Role in Solar Advancement
To measure solar energy's profound impact, we must contemplate the “carbon footprint” — a metric that quantifies the total greenhouse gas emissions caused by an individual, organization, event, or product. Traditional electricity production contributes heavily to a nation's footprint, with fossil fuels being the predominant energy source. By harnessing solar energy, we offset these emissions and aid in the progressive decline of our collective carbon footprint.
In the battle against climate change, the shift towards renewable energy sources plays a pivotal role. Among these, solar energy emerges as a beacon of hope and innovation. Positioned as both a clean and inexhaustible source of power, solar energy has shown significant promise in reducing global carbon emissions. Let’s explore how the adoption of solar power is making strides in the journey towards a more sustainable future.
Active participation from both consumers and industries in the solar movement is imperative. It includes transitioning to solar power where feasible, supporting policies that encourage
