對(duì)于常見的工程應(yīng)用來說，計(jì)算的工況很多，尤其優(yōu)化工作，少則幾百，多則上千，面對(duì)如此之多的case文件要寫，假如按照一個(gè)一個(gè)的讀寫的話，相信你一定會(huì)為這么機(jī)械的工作煩躁，甚至影響今后好幾天的心情，那么有什么簡便一些的方法呢？答案是肯定的。那就是采用 fluent的journal文件。
首先打開fluent軟件，在file/write/start journal，見下圖：

選擇保存文件名*.journal后（看你自己怎么設(shè)置文件名），我一般按照這一組的類型來命名；
這樣， journal文件就開始記錄你以后的每一步操作。
按照原先設(shè)置模型參數(shù)一樣，一步步來就是了。
等你操作完成后，原先的”start journal“現(xiàn)在已經(jīng)是”stop journal“，所以你只需要選擇”stop journal“就可以了。
此時(shí)，用寫字板打開看看就可以看到如下的一些記錄命令。

這樣一個(gè)case文件就寫完了，你后面需要做的就是替換"fluent.msh"與"fluent.cas“為你自己的文件名就行。復(fù)制粘貼寫好的一個(gè)case的journal文件，替換成下一個(gè)mesh文件名；值得注意的是，模型文件中的邊界數(shù)量要一致，否則會(huì)出現(xiàn)錯(cuò)誤，因?yàn)镚UI語言是按照fluent里邊界的ID號(hào)來識(shí)別的。
基本上，這樣寫case文件還是很省事的，你到時(shí)就可以在一邊聽著音樂，一邊看著它自動(dòng)編寫！
