WebWe show how the original D3Q19 MRT-CM (d’Humi`eres version) leads to unrealistic kinetic energy accumulation at high wave numbers, whilst our optimized MRT-CM provides the correct energy dissipated rate, avoiding energy build up at high wavenumbers. These results suggest that our optimization strategy enhances WebDec 10, 2024 · Implementation of MRT-LBE D3Q19 model.
