本文详细介绍如何在Ubuntu环境下配置OpenFOAM，涵盖从安装Ubuntu OpenMPI到OpenFOAM的步骤，为用户提供了清晰的指南，助力高效完成环境搭建。

本文目录导读：

  1. 系统要求
  2. 安装步骤

在科学计算领域，OpenFOAM（Open Source Field Operation and Manipulation）是一款功能强大的开源流体动力学模拟软件，本文将为您详细介绍如何在Ubuntu操作系统上安装和配置OpenFOAM，帮助您顺利搭建一个适用于流体力学研究的计算环境。

系统要求

在开始安装OpenFOAM之前，请确保您的Ubuntu系统满足以下要求：

1、操作系统：Ubuntu 18.04/20.04

2、GCC版本：4.9及以上

3、CMake版本：3.3.2及以上

4、Python版本：2.7或3.x

安装步骤

1、更新系统

打开终端，输入以下命令更新系统：

sudo apt update
sudo apt upgrade

2、安装依赖包

OpenFOAM依赖于一些第三方库，需要安装以下依赖包：

sudo apt install -y git cmake g++ libopenmpi-dev libfftw3-dev libmpfr-dev libboost-all-dev libeigen3-dev

3、下载OpenFOAM源代码

从OpenFOAM官网（https://openfoam.org/download/）获取最新版本的源代码，这里以OpenFOAM 9为例：

cd ~
git clone https://github.com/OpenFOAM/OpenFOAM-9.git

4、编译OpenFOAM

进入OpenFOAM源代码目录，创建一个构建目录并切换到该目录：

cd ~/OpenFOAM-9
mkdir build
cd build

使用CMake编译OpenFOAM：

cmake ..
make -j $(nproc)

这里-j $(nproc)表示使用所有CPU核心进行编译，以加快编译速度。

5、配置环境变量

将OpenFOAM添加到系统环境变量中，编辑~/.bashrc文件，添加以下内容：

export PATH=$PATH:/home/username/OpenFOAM-9/platforms/linux64GccDPInt64Opt/bin
export WM_PROJECT_VERSION=9
export WM_PROJECT_DIR=$HOME/OpenFOAM-9
