After the solution of several such units, certain weighed average technique should be taken to obtain the griddirection for the whole simulated layer and the whole model.
求解出若干基本单元后，进行某种加权平均，可得到模拟层及整个模型的网格方向。

It's not hard to see why State Grid would want to move in that direction.
国家电网为什么希望朝着这个方向行进，其实不难想象。

The pseudo diffusion can be effectively reduced by using a grid system which is consistent with the flow direction.
