1、虚拟机
我这里使用的是开源linux系统Ubuntu22.0，可以使用VMware来安装。自行百度
2、添加镜像源并更新
打开sources.list文件
sudo gedit /etc/apt/sources.list
删除全部内容，添加清华镜像源。

更新源
sudo apt update
如果源使用不对，可能会出现工具版本不对应的问题
4、依赖安装
sudo apt-get install -y build-essential flex bison git-core cmake zlib1g-dev libboost-system-dev libboost-thread-dev libopenmpi-dev openmpi-bin gnuplot libreadline-dev libncurses-dev libxt-dev
5、安装openfoam
cd $HOME // 进入Home文件夹
mkdir OpenFOAM // 创建OpenFOAM文件夹
cd OpenFOAM // 进入OpenFOAM文件夹
git clone https://e.coding.net/dyfluid/OpenFOAM/OpenFOAM-9.git && git clone https://e.coding.net/dyfluid/OpenFOAM/ThirdParty-9.git // 克隆openfoam
将openfoam添加到源文件
source OpenFOAM-9/etc/bashrc &&
cd OpenFOAM-9 &&
./Allwmake -j &&
sed -i '$a source $HOME/OpenFOAM/OpenFOAM-9/etc/bashrc' $HOME/.bashrc
