Lattice Boltzmann methods (LBM) is a class of computational fluid dynamics (CFD) methods that is a trustworthy alternative to conventional CFD. In several engineering applications, they have shown to be roughly an order of magnitude faster than Navier-Stokes approaches in comparable scenarios. LBM are also well suited to exploit advanced supercomputer architectures through vectorisation, hardware accelerators and massively parallel computers. The EU-funded SCALABLE project will gather prominent industrial and academic partners to achieve unprecedented performance, scalability and energy efficiency of an industrial LBM-based CFD software.
