OpenFOAM官方推荐的首选系统是ubuntu，在ubuntu下安装OpenFOAM巨简单。可是MAC系统下，官方推荐是通过Docker虚拟ubuntu系统进行，但是这有几个弊端：虚拟机下运行效率低；访问不方便；数据共享很麻烦。找了很久终于找到了在Mac下安装的方法——源码安装。
教程
完全按照OpenFOAM(R) on OS X不找安装就没问题。
但是在安装scotch和brew install parmetis总是失败，突然想到我电脑上之前安装了dealii。dealii的安装目录下有自己的brew程序，而且已经将一些主要的库打包在了brew的安装目录下面。所以所有的这些安装都启用dealii的brew(而不是系统的brew)安装即可。
brew所在路径:/Applications/deal.II-8.5-brew.app/Contents/Resources/brew/bin/brew
注：之前安装完dealii发现系统自动将brew定向到dealii的brew，为了使dealii安装之前的程序有效，我将dealii的brew改名为brew2来阻止他的调用，因为dealii的brew安装的软件全都在装到了/Applications/deal.II-8.5-brew.app/Contents/Resources/brew目录下面。现在为了安装OpenFOAM决定由改回来，以后也不会变，就让他装在dealii目录下面好了。
