问一下非平衡反弹格式这个边界处理

michaelccm

为什么在这个边界上，f0 f1 f3 f7 f4 f8是已知的，而f2 f5 f6是未知的。。
谢谢大家指点我一下，看书没多久，很多不懂的。

f_4, f_7, and f_8 come from the flow domain AFTER advection, therefore they are known.
the reverse of them, i.e., f_2, f_5, and f_6, are unknown because they are coming from
outside of flow domain, thus need to be re-constructed. Bounce-back is the SIMPLEST
way to do so. Also, f_0, f_1, and f_3 are irrelevant.
