这一贡献提出了一种替代的晶格玻尔兹曼网格细化算法，克服了困扰现有方法的缺点。我们证明了该算法是准确的，适用于所有的松弛时间值。结果表明，该算法可以显著加快水流沉降过程。通过使用网格层次结构，可以比单个网格分辨率快一千倍地接近静止状态。
This contribution proposes an alternative lattice Boltzmann grid refinement algorithm that overcomes the drawbacks that plague existing approaches. We demonstrate that this algorithm is accurate and applicable for all values of the relaxation time. We also show that this algorithm can significantly speed up the flow settlement process. By using a hierarchy of grid levels, the stationary regime can be approached up to a thousand times faster than with a single grid resolution.
