This is particularly interesting, because normally, in classical fluid simulations, if our grid resolution is insufficient, we typically encounter water volume dissipation, which means that the total amount of mass in the simulation decreases over time.

这特别有趣，因为一般在经典流体模拟中，如果网格方案有所不足，我们将会遇到的典型问题是水的体积损耗，这意味着模拟中的总质量会随着时间的推移而减少。
