It received support from the competitiveness clusters Systematic and LUTB. The project aims at developing innovative HPC (High Performance Computing) methods and tools allowing multiphysics simulations in CFD (Computational Fluid Dynamics). By bringing together players from the entire value chain, the ambition of the project is to develop and federate technological bricks in the following areas:

  • High performance computing: new-generation processors, infrastructure management, HPC services.
  • Computational fluid dynamics: innovative algorithms, high-fidelity numerical models and state-of-the-art pre and post-processing tools.
  • Multiphysics simulations within an industrial context: software coupling, complex workflow management.

All the research and development carried out in CLIMB is based on ProLB (previously called LaBS), a Lattice Boltzman CFD solver.

This project helped DISTENE to address some of the complex issues faced by the Automotive and Aerospace industry when using CFD for Aerodynamic and Aeroacoustic applications. In particular, DISTENE has improved the capabilities of its MeshGems technology, especially in the field of CFD applications, so as to:

  • improve MeshGems’ capabilities to address meshing needs of solvers based on the LBM approach as well as to clean dirty CAD geometries for a successful meshing workflow,
  • provide new options and workflows to automatically close non-watertight volumes, such as the external fluid domain surrounding the outside of a car for Aerodynamics studies. This has to be closed to get rid of the “real world” car body artifact, like spaces between the body and the doors, which have to be “stitched” or glued prior to the computation.

Our thanks go to all the partners of the project and to the French Government for his support to DISTENE in being the leading provider of Meshing Software Technologies worldwide.

We d’ like to also address our special thanks to Matelys, one of the Partners of the CLIMB project, who, as a result of this project are now using and licensing MeshGems to be a Gem of the software they developed for the modelling of porous media. All our best wishes of success!
