OpenFOAM（Open Source Field Operation and Manipulation）是一款开源的流体力学模拟软件，广泛应用于计算流体动力学（CFD）领域，在Ubuntu操作系统上配置OpenFOAM，可以充分利用Linux系统的稳定性和高性能，本文将详细介绍在Ubuntu系统下配置OpenFOAM的步骤。

系统要求

1、操作系统：Ubuntu 18.04/20.04 LTS

2、硬件要求：64位处理器，至少4GB内存，建议使用SSD硬盘以提高性能

3、编译工具：g++（C++编译器），make（构建工具）

安装依赖包

在配置OpenFOAM之前，需要先安装一些依赖包，打开终端，执行以下命令：

sudo apt-get update
sudo apt-get install g++ make git cmake libopenmpi-dev libmpich-dev libparmetis-dev

下载OpenFOAM源码

1、访问OpenFOAM官网（https://openfoam.org/），找到最新版本的源码下载链接。

2、使用wget命令下载源码包，

wget https://sourceforge.net/projects/openfoam/files/OpenFOAM-9/9.0.1/openfoam-9.0.1.tar.gz/download

3、下载完成后，使用tar命令解压源码包：

tar -xzf openfoam-9.0.1.tar.gz

编译OpenFOAM

1、进入解压后的源码目录：

cd openfoam-9.0.1

2、创建一个构建目录并进入：

mkdir build
cd build

3、使用cmake命令配置项目：

cmake ..

4、编译OpenFOAM：

make

5、安装OpenFOAM：

sudo make install

配置环境变量

1、打开终端，编辑用户的bash配置文件（.bashrc）：

nano ~/.bashrc

2、在文件末尾添加以下内容：

export WM_PROJECT_DIR=$HOME/openfoam-9.0.1
