GAC engineers used Altair CFD’s Lattice Boltzmann method (LBM) solver to perform hundreds of transient simulations on design changes with high-accuracy using NVIDIA’s Tesla-V100 GPUs to increase computing efficiency. Results include achieving one of the highest aerodynamic efficient vehicle designs in its class on the GAC GS4 coupe, and on the concept GAC ENO.146, while at the same time realizing model preparation time savings of 60% and simulation cost savings of 70%.
