P1 - D2.4 Report on Reference Applications Outcomes


Public material


The EXCELLERAT project was established in December 2018 to create a European Centre of Excellence (CoE) for Engineering Applications to meet the challenges of the fourth wave of industrialisation and to support European engineering companies in their use of HPC and HPDA, thus increasing European industrial competitiveness. The CoE was focused on a set of engineering software applications which were chosen to drive the technical developments necessary to progress the codes towards Exascale. A further objective of the project was to develop a service-oriented methodology to transfer knowledge and expertise to the wider engineering HPC community, while at the same time providing a potential route to sustainability for the CoE. This document reports on the work done directly on the chosen applications to develop them for Exascale.

The application codes selected were:

  • Nek5000: Open source spectral code that solves the incompressible Navier-Stokes with a number of additional physics (heat transfer, magneto-hydrodynamics, low Mach number, electrostatics)
  • ALYA: HPC Multiphysics code that uses Finite Element Method for large scale problems with complex geometries
  • AVBP: Finite element/volume 3D compressible flow solver using unstructured grids and capable of Large Eddy Simulation (LES)
  • TPLS: Open-source solver for the incompressible Navier-Stokes equations for a two fluid flow, using the level-set method to identify interfaces
  • FEniCS: Open-source high-level problem solving environment for automated solution of PDEs by the finite element method
  • CODA: CFD solver for Aircraft design. Specific requirements for Exascale e.g. multi-level-parallelization and asynchronous execution.
