- The domain is divided twice in two-grid method.At first, divide the domain into coarse gird.A nonlinear problem is solved on this coarse grid. 兩重網格演算法是先在粗網格上計算一個非線性問題,然後將粗網格細分,再在細網格上計算一個線性問題。
- Using coarse grids can improve calculative efficiency. 採用粗網格可以提高計算效率。
- So in this paper, we use a much more robust algorithm, Hooke-Jeeves pattern search method, to solve the problem on the coarse grid, and the faster method: Polack-Ribiere conjugate gradient method or SSC gradient method on the finer grid. 故在本文中採用更為健壯的Hooke-Jeeves模式搜索法在粗網格上進行求解，得到一個較好的初值，然後再採用速度較快Polack-Ribiere共軛梯度法或不含線搜索的SSC梯度法在細網格上進行磨光，這樣既保證了方法的收斂，又保證了速度。

- FCT yields more accurate solution for increasing order of differencing approximations.Moreover, it results in a net computation savings for allowing coarser grids. FCT方法用於高階差分既具有較高的計算精度，又因適應採樣間隔較大的情況而節省了計算量，從而具有較高的計算速度。
