Illuminating the future of numerical modelling

The field of Computational Fluid Dynamics (CFD) covers a diverse number of areas, from weather prediction, to vehicle design, to modelling the heat flow through buildings. What level of accuracy that can be achieved in the model is often a function of the available compute power - which is now a major limiting factor. Furthermore, the volumes of data produced by large models commonly require sampling due to their size. The Optalysys technology is being developed to solve these problems.

  Our most notable development has been as part of the ESCAPE project, detailed below. 


Project ESCAPE

Numerical Weather Prediction


Optalysys is part of a major project led by the European Centre for Medium-Range Weather Forecasts (ECMWF) to develop the next generation platform for numerical weather prediction.



  • An exascale HPC system using Optalysys technology that can run the next generation of numerical weather prediction algorithms in an energy-efficient way.


  • Successfully awarded a €4m grant by the European Commission through its Horizon 2020 Research and Innovation programme.
  • Started 1st October 2015.
  • See project website for most recent updates.
  • In June we presented a demonstration of the optical spherical harmonic transform system to the EU at the mid-term project review meeting in Reading. This work has produced a novel method of generating functions using our optical approach which was not previously possible.
