The geometry is a set of hexahedral solids which have a logical representation. Each block in the geometry is called a ‘solid’. Each solid in the geometry can represent a fluid, porous or solid region

Simplify the problem - Simplify geometry > Ignore features that do not affect the flow > Use as many blocks as possible to set the geometry > Make blocks meet at complete faces

路由器的工作过程：从某个端口收到一个数据包，它首先 把链路层的包头去掉（拆包），读取目的IP地址，然后查找路 由表，若能确定下一步往哪送，则再加上链路层的包头（打 包），把该数据包转发出去；如果不能确定下一步的地址，则 向源地址返回一个信息，并把这个数据包丢掉
