fluent批量处理——模型参数…

对于常见的工程应用来说，计算的工况很多，尤其优化工作，少则几百，多则上千，面对如此之多的case文件要写，假如按照一个一个的读写的话，相信你一定会为这么机械的工作烦躁，甚至影响今后好几天的心情，那么有什么简便一些的方法呢？答案是肯定的。那就是采用fluent的journal文件。
首先打开fluent软件，在file/write/start journal，见下图：

选择保存文件名*.journal后（看你自己怎么设置文件名），我一般按照这一组的类型来命名；
这样， journal文件就开始记录你以后的每一步操作。
按照原先设置模型参数一样，一步步来就是了。
等你操作完成后，原先的”start journal“现在已经是”stop journal“，所以你只需要选择”stop journal“就可以了。
此时，用写字板打开看看就可以看到如下的一些记录命令。

这样一个case文件就写完了，你后面需要做的就是替换"fluent.msh"与"fluent.cas“为你自己的文件名就行。复制粘贴写好的一个case的journal文件，替换成下一个mesh文件名；值得注意的是，模型文件中的边界数量要一致，否则会出现错误，因为GUI语言是按照fluent里边界的ID号来识别的。
基本上，这样写case文件还是很省事的，你到时就可以在一边听着音乐，一边看着它自动编写！
