An orthogonalization procedure for structured grids 一種簡單的結(jié)構(gòu)網(wǎng)格邊界正交化方法
The material job and main conclusion are as follows : ( 1 ) a simple boundary orthogonalization procedure independence grids generation method is put forward on the base of algebraic grid generation method ; data structure and computational model on interface are established aiming at blocks of structured grids . ( 2 ) simple procedure is established in nonorthogonal grids by use of the finite volume method and in - depth discusses on special topic such as boundary condition in nonorthogonal grids , deferred correction method and grads compute on calculational nodes , and so on 本文完成的具體工作和主要結(jié)論如下: 1 )以代數(shù)網(wǎng)格生成方法為基礎(chǔ)提出了一種簡單的、可獨(dú)立于網(wǎng)格生成方法之外的邊界正交化技術(shù);針對(duì)分區(qū)結(jié)構(gòu)網(wǎng)格系統(tǒng)建立了分區(qū)交界面處的數(shù)據(jù)結(jié)構(gòu)與計(jì)算模型; 2 )利用有限體積方法在非正交同位網(wǎng)格系統(tǒng)中建立了simple求解算法,對(duì)非正交網(wǎng)格系統(tǒng)中的邊界條件、延遲修正技術(shù)及計(jì)算節(jié)點(diǎn)的梯度計(jì)算等專題進(jìn)行了深入討論。
