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：
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=$HOME/OpenFOAM-9 export WM_THIRD_PARTY_DIR=$WM_PROJECT_DIR/thirdParty export WM_CGAL_DIR=$WM_THIRD_PARTY_DIR/cgal-4.7 export WM_FREETYPE_DIR=$WM_THIRD_PARTY_DIR/freetype-2.9.1 export WM_MXML_DIR=$WM_THIRD_PARTY_DIR/mxml-2.9 export WM_ZLIB_DIR=$WM_THIRD_PARTY_DIR/zlib-1.2.11 export WM_EIGEN_DIR=$WM_THIRD_PARTY_DIR/eigen-3.3.7 export WM sodomex_DIR=$WM_THIRD_PARTY_DIR/sodomex-1.0 export WM_LAPACK_DIR=/usr/lib/x86_64-linux-gnu export WM_BLAS_DIR=/usr/lib/x86_64-linux-gnu export WM_compiler_GNUarch=64 export WM_COMPILER_TYPE=GCC export WM_PRECISION=DP export WM_LABEL_SIZE=64 export WMarchingCubes=ON export WMOpenGL=ON export WM_LMMesh=ON export WM_FVMesh=ON export WM_Mesh=ON export WM_Eigen=ON export WM_ScalarTransport=ON export WM_Compressible=ON export WM_Reacting=ON export WM_Multifluid=ON export WM_Parallel=ON export WMкачать=ON export WM_OMesh=ON export WM_overset=ON export WM_runTime=ON export WM_ams=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON export WM_X Wire=ON
