本文介绍了在Ubuntu操作系统下如何配置与安装OpenFOAM。指南详细阐述了安装过程中的各个步骤，包括依赖关系的解决、OpenFOAM源代码的下载、编译以及环境变量的配置，旨在帮助用户顺利地在Ubuntu上搭建OpenFOAM计算环境。
本文目录导读：
随着计算机辅助工程（CAE）的快速发展，OpenFOAM 作为一款开源的计算流体动力学（CFD）软件，受到了越来越多科研人员和工程师的青睐，本文将详细介绍如何在 Ubuntu 操作系统下配置和安装 OpenFOAM，帮助读者顺利搭建 CFD 模拟环境。
系统要求
在开始配置 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 或更高版本
2、CPU：64 位处理器
3、内存：至少 4GB
4、硬盘：至少 20GB 的可用空间
安装依赖
1、安装编译器
打开终端，输入以下命令安装编译器：
sudo apt-get update sudo apt-get install g++ gfortran
2、安装并行计算库
OpenFOAM 支持并行计算，因此需要安装并行计算库，输入以下命令安装：
sudo apt-get install mpich libmpich-dev
3、安装其他依赖
OpenFOAM 还需要以下依赖库，输入以下命令安装：
sudo apt-get install cmake git gitk libopenmpi-dev libfftw3-dev libeigen3-dev libboost-all-dev
下载 OpenFOAM
1、访问 OpenFOAM 官方网站（https://openfoam.org/），下载最新版本的源代码。
2、将下载的压缩包解压到指定目录，例如/opt/openfoam。
编译 OpenFOAM
1、打开终端，进入 OpenFOAM 源代码目录。
2、创建一个名为Allwmake 的脚本文件，并输入以下内容：
