How aerodynamic is Boeing 747 at Re=50k? (Nvidia A100)

This is a quick FluidX3D CFD simulation of the Boeing 747. Re=50k, eye-watering 912×1824×456 resolution, 100k time steps, 6h34min compute+render time on an A100 40GB GPU. Rendering: velocity-colored Q-criterion at Q=0.00002. My FluidX3D code is standard lattice Boltzmann method (LBM), D3Q19, BGK collision, simple mid-grid bounce-back boundaries. For the box walls I use equilibriium boundaries. My implementation is ultra (memory) efficient with Esoteric-Pull streaming and FP16 memory compression, reducing memory demand to 55 Bytes/node, 1/3 of other FP32 implementations. This way I can get extremely large resolution even on a single GPU with limited memory capacity.
