Ubuntu18.04更新至20.04 OpenFOAM无法正常使用
-
然后还想附上一直想发出来的，之前安装三个版本的openfoam历程，欢迎大家修改完善
OpenFOAM安装
Overview
系统版本：Ubuntu18.04 LTS
安装方式：编译安装
安装版本：OpenFOAM-7、foam-extend 4.1、OpenFOAM-V1902
参阅：
多版本共存方式
-
终端输入
gedit $HOME/.bashrc -
方法1
在文件的最底部重新取一行添加下述两行文字：
alias of3x="source ~/OpenFOAM/OpenFOAM-3.x/etc/bashrc" alias of4x="source ~/OpenFOAM/OpenFOAM-4.x/etc/bashrc" -
方法2
在文件的最底部添加：
# source $HOME/OpenFOAM/OpenFOAM-7/etc/bashrc source $HOME/foam/foam-extend-4.1/etc/bashrc # source $HOME/OpenFOAM/OpenFOAM-v1912/etc/bashrc -
方法3 (采用)
source $HOME/OpenFOAM/OpenFOAM-7/etc/bashrc alias of19='source $HOME/OpenFOAM/OpenFOAM-v1912/etc/bashrc' alias fe41='source $HOME/OpenFOAM/foam-extend-4.1/etc/bashrc'
OpenFOAM-7（大致耗时一下午5~6h）
安装of7
-
确保ubuntu可以联网，启动终端，在终端输入（分三次输入，直接全部复制进去）：
# 更新软件 sudo apt update # 安装依赖1 sudo apt-get install build-essential flex bison git-core cmake zlib1g-dev libboost-system-dev libboost-thread-dev libopenmpi-dev openmpi-bin gnuplot libreadline-dev libncurses-dev libxt-dev # 安装依赖2 sudo apt-get install qt4-dev-tools libqt4-dev libqt4-opengl-dev freeglut3-dev libqtwebkit-dev -
下载OpenFOAM-7.tar以及ThirdParty-7.tar，然后从窗口进入到ubuntu系统的Home文件夹下建立文件夹为OpenFOAM。
-
进入这个OpenFOAM文件夹，将下载的OpenFOAM-7.tar复制进去右键解压缩会出现一个OpenFOAM-7-master的文件夹。去掉master后缀改名为OpenFOAM-7。同样把ThirdParty-7.tar解压缩至此处，去掉master后缀改名为ThirdParty-7文件夹。注意，两个文件夹缺一不可。否则会提示缺少相关文件编译error。
-
配置环境变量：在终端输入
gedit $HOME/.bashrc会打开一个文件，我们在文件的最底部重新取一行添加下述文字：
source $HOME/OpenFOAM/OpenFOAM-7/etc/bashrc保存并关闭。关闭终端并打开新的终端的时候，环境变量自动生效。
-
配置并行编译
在OpenFOAM目录下的etc下打开bashrc文件，在其中最底部添加
export WM_NCOMPPROCS=4表示采用4核并行编译。用户可以随意更改其中的数字。
-
编译OpenFOAM：打开终端，输入（即切换到OpenFOAM-7目录下）：
cd $HOME/OpenFOAM/OpenFOAM-7/然后输入：
./Allwmake这时候会输出大量的信息，编译开始。编译之后请尝试运行：

编译安装Paraview
-
终端切换到ThirdParty-7目录下并键入：
sudo apt-get install qt5-default libqt5x11extras5-dev qttools5-dev curl -
终端键入：
./makeParaView其中会自动下载ParaView并开始编译，编译过程较长。编译完成后会显示Installation complete for paraview-5.4.0等信息。
-
分四次键入
wmRefresh cd $FOAM_UTILITIES/postProcessing/graphics/PVReaders ./Allwclean ./Allwmake将会再次开始编译过程。几分钟即编译完成。然后键入paraFoam即可运行。
foam-extend 4.1
安装fe41
-
确保Ubuntu可以联网
# 更新 sudo apt-get update # 安装依赖 sudo apt-get install git-core build-essential binutils-dev cmake flex \ zlib1g-dev qt4-dev-tools libqt4-dev libncurses5-dev curl bison \ libxt-dev rpm mercurial graphviz python python-dev python3 python3-dev然而这样并不能成功安装，继续安装一些依赖
sudo apt-get install openmpi-bin libopenmpi-dev #Addition: Use system installed OpenMPI sudo apt install curl #Addition: Needed for downloading of ThirdPartyProducts -
设置一下
echo "export WM_THIRD_PARTY_USE_BISON_27=1" > etc/prefs.sh #Compile bison-2.7 echo "export WM_MPLIB=SYSTEMOPENMPI" >> etc/prefs.sh #Addition: Use system installed OpenMPI echo "export OPENMPI_DIR=/usr" >> etc/prefs.sh #Addition: Use system installed OpenMPI echo "export OPENMPI_BIN_DIR=\$OPENMPI_DIR/bin" >> etc/prefs.sh #Addition: Use system installed OpenMPI See the etc/prefs-sh-EXAMPLE file for more examples on how to do modifications. source etc/bashrc echo "alias fe41='source \$HOME/foam/foam-extend-4.1/etc/bashrc'" >> $HOME/.bashrc -
编译(四核编译时间大概3~4小时)
./Allwmake.firstInstall -
测试安装
# Test the installation: # Press CTRL-ALT-T to open an new terminal window fe41 mkdir -p $FOAM_RUN run # 如果下一步没有成功请手动复制 cp -r $FOAM_TUTORIALS/incompressible/icoFoam/cavity cd cavity blockMesh
运行结果：

绿色版ParaView安装非常简单，并且在处理网格较多的算例比编译版本的paraFoam要快。用户可以在ParaView官方（或本链接 Paraview-5.8.0）直接下载linux版本的ParaView绿色版，随意解压缩到任意的文件夹，双击打开ParaView/bin/paraview文件即可运行（如下图）。在打开ParaView之后，在任意的OpenFOAM算例下创建一个空文件并命名为case.foam，然后用ParaView打开这个文件即可。
OpenFOAM-V1902
