In SCALABLE project eminent industrials and academic partners team up to improve the performance, scalability, and energy efficiency of an industrial Lattice Boltzmann methods-based computational fluid dynamics (CFD) software. Lattice Boltzmann methods (LBM) have already evolved to become trustworthy alternatives to conventional CFD. LBM is especially well suited to exploit advanced supercomputer architectures through vectorization, accelerators, and massive parallelization. The project will directly benefit the European industry, while contributing to fundamental research.
