Computational Fluid Dynamics

Large-eddy simulation of turbulent flows, multiphase flows and aeroacoustic modelling of wind turbines.

AI & Physics-Based Models

Combination of physics-based models with AI for industrial process optimisation, surrogate modelling and data-driven inference.

Scientific Approach

Physics-Based Modelling and Simulation

Our models and simulations are grounded in the laws of physics. We develop and apply mathematical methods, including robust, parallel and adaptive multigrid solvers for partial differential equations, to tackle large-scale problems that are intractable with standard approaches.

Where appropriate, we complement our physics-based methods with machine learning, for example to accelerate development workflows or to enhance existing simulation pipelines.
