The main process of the method is : after the converged solution for a certain layer of grid is obtained, all elements that are required to be refined based on error analysis are automatically found and output. as the distribution of the elements to be refined is often discrete and irregular, regular square blocks consisting of elements to be refined need to be manually built and input to the computer. the computation for the refined layer grid is then carried out and the procedure is repeated until the final convergence criterion is satisfied
該方法的特點是：當某一層次網格取得收斂解后，程序根據誤差分析自動判別並輸出該層次網格內需加密的單元，由於需加密單元的分佈一般較為離散和不規則，因此通過人工介入對這些單元進行組塊並輸入到計算機，程序便開始進行下一層次網格的迭代計算，直至得到滿足最終收斂判據的解。 -
