OpenFOAM求解器和库函数简介-摩杜云开发者社区

首先，通过命令 foam 进入OpenFOAM的环境

ran@ran:~$ foam
ran@ran:~/OpenFOAM/OpenFOAM-10$

可以看见，现在我们已经进入当前版本的主文件：/OpenFOAM/OpenFOAM-10

那么这个命令foam实际上是一个所谓的alias或者叫快捷方式，

在OpenFOAM环境下，它定义了若干个快捷方式，我们可以在一个文件里面找到它们所有的定义

通过以下命令可以查看

ran@ran:~/OpenFOAM/OpenFOAM-10$ vim etc/config.sh/aliases

主要用到的快捷方式有以下这些:

OpenFOAM求解器和库函数简介_openfoam

alias src='cd $FOAM_SRC'
alias lib='cd $FOAM_LIBBIN'
alias app='cd $FOAM_APP'
alias sol='cd $FOAM_SOLVERS'
alias util='cd $FOAM_UTILITIES'
alias tut='cd $FOAM_TUTORIALS'
alias run='cd $FOAM_RUN'

可以看见，快捷方式调用了相应的环境变量，如：$FOAM_SRC

如果想知道环境变量的地址，可以通过echo命令来查看

ran@ran:~/OpenFOAM/OpenFOAM-10$ echo $FOAM_SRC
/home/ranyan/OpenFOAM/OpenFOAM-10/src

当我们输入相应的快捷命令，便可以进入对应的文件夹，通过 ls 命令可以查看文件：

src：库函数文件夹

tut：算例文件夹，若算例使用相同的求解器，会放在同一个文件夹下。

ran@ran:~/OpenFOAM/OpenFOAM-10$ tut
ran@ran:~/OpenFOAM/OpenFOAM-10/tutorials$ ls
Allclean  Alltest  combustion    discreteMethods  electromagnetics  heatTransfer    lagrangian  multiphase  stressAnalysis
Allrun    basic    compressible  DNS              financial         incompressible  mesh        resources

run：刚安装好时，这个文件夹是不存在的，可以通过下面命令创建

mkdir -p $FOAM_RUN

建议：为了防止你无意间修改官方的源程序，自己所有的算例、包括库函数，都放到这个文件夹下，保证FOAM稳定。

下面我们来主要介绍求解器文件夹：
