最近装了OpenFOAM-v2112，记录一下，利人利己。

安装系统

虚拟机

1. ubuntu 20.04，VMware，很多安装教程

2. 换源：阿里源

进入Ubuntu桌面，终端输入

sudo gedit /etc/apt/sources.list

将内容全部删除，并将下面的内容粘贴进去，并保存

deb / focal main restricted universe multiverse
deb-src / focal main restricted universe multiverse
deb / focal-security main restricted universe multiverse
deb-src / focal-security main restricted universe multiverse
deb / focal-updates main restricted universe multiverse
deb-src / focal-updates main restricted universe multiverse
deb / focal-proposed main restricted universe multiverse
deb-src / focal-proposed main restricted universe multiverse
deb / focal-backports main restricted universe multiverse
deb-src / focal-backports main restricted universe multiverse

安装OpenFOAM-v2112

安装依赖

1. 可参考OpenFOAM官网给出的OpenFOAM系统要求

sudo apt-get update
sudo apt-get install build-essential autoconf autotools-dev cmake gawk gnuplot
sudo apt-get install flex libfl-dev libreadline-dev zlib1g-dev openmpi-bin libopenmpi-dev mpi-default-bin mpi-default-dev
sudo apt-get install libgmp-dev libmpfr-dev libmpc-dev

2. 安装openmpi，参考链接

• 进入openmpi官网，选择Download，鼠标右击openmpi-4.1.2.tar.gz上复制下载链接
  

• 终端输入

wget .1/openmpi-4.1.2.tar.gz

• 解压

tar -zxvf openmpi-4.1.2.tar.gz

• 打开openmpi-4.1.2

cd openmpi-4.1.2

• 配置（将其安装到 /usr/local/openmpi目录下）

./configure --prefix="/usr/local/openmpi"

• Build 并安装

make

sudo make install

• 设置环境变量 gedit ~/.bashrc，打开后末尾输入

export PATH="$PATH:/usr/local/openmpi/bin"
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/openmpi/lib/"

• 保存后执行

sudo ldconfig

打开新的终端，使环境变量生效

• 测试是否安装成功

mpirun 

设置环境变量

sudo gedit ~/.bashrc

alias of2112='source ~/OpenFOAM/OpenFOAM-v2112/etc/bashrc'

编译系统

of2112
foamSystemCheck
foam
./Allwmake -j -s -q -l
foamInstallationTest

测试

mkdir -p $WM_PROJECT_USER_DIR/{run,applications,src}
run
cp -r $FOAM_TUTORIALS/incompressible/simpleFoam/pitzDaily ./
cd pitzDaily
blockMesh
simpleFoam

Paraview安装

1. 可以安装编译版paraFoam：

cd ThirdParty-v2112
./makeParaView

paraFoam

2. 这里是从官网下载，手动安装了paraview-5.10.0

• 进入ParaView官网，下载
  

• 将ParaView压缩包拷贝到home目录下并解压

tar -zxvf ParaView-5.10.0-MPI-Linux-Python3.9-x86_64.tar.gz

• 重名为ParaView-5.10.0，并将其拷贝到/opt目录下

mv ParaView-5.10.0-MPI-Linux-Python3.9-x86_64 ParaView-5.10.0
cp -r ParaView-5.10.0 /opt/

• 设置环境变量 sudo gedit ~/.bashrc，末尾添加

export PATH=$PATH:/opt/ParaView-5.10.0/bin

• 然后在运行完算例后 touch xxx.foam，paraview xxx.foam 就可以了
