已经安装了部分环境，所以以下步骤综合了几个教程，未经过完全的验证。

配置环境

 sudo apt-get install g++-7 gcc-7
 sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-7 7
 sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-7 7
 sudo update-alternatives --config gcc
 sudo update-alternatives --config g++

sudo apt-get update
sudo apt-get install build-essential flex bison cmake zlib1g-dev libboost-system-dev libboost-thread-dev \
libopenmpi-dev openmpi-bin gnuplot libreadline-dev libncurses-dev libxt-dev \

下载安装包，设置环境

cd ~
mkdir OpenFOAM
cd OpenFOAM
wget "http://downloads.sourceforge.net/openfoamplus/files/OpenFOAM-v1706.tgz?use_mirror=mesh" -O OpenFOAM-v1706.tgz
wget "http://downloads.sourceforge.net/openfoamplus/files/ThirdParty-v1706.tgz?use_mirror=mesh" -O ThirdParty-v1706.tgz
 
tar -xzf OpenFOAM-v1706.tgz
tar -xzf ThirdParty-v1706.tgz

ln -s /usr/bin/mpicc.openmpi OpenFOAM-v1706/bin/mpicc
ln -s /usr/bin/mpirun.openmpi OpenFOAM-v1706/bin/mpirun

source $HOME/OpenFOAM/OpenFOAM-v1706/etc/bashrc WM_LABEL_SIZE=64

echo "alias of1706+='source \$HOME/OpenFOAM/OpenFOAM-v1706/etc/bashrc $FOAM_SETTINGS'" >> $HOME/.bashrc

source $HOME/.bashrc
of1706+

安装ParaView

cd $WM_THIRD_PARTY_DIR
export QT_SELECT=qt5

./makeParaView -python -mpi -python-lib /usr/lib/x86_64-linux-gnu/libpython2.7.so.1.0 > log.makePV 2>&1

检查log.makePV，遇到错误：

make: *** [Makefile:152：all] 错误 2
Command exited with non-zero status 2
227.09user 49.42system 0:37.28elapsed 741%CPU (0avgtext+0avgdata 340836maxresident)k
134096inputs+260440outputs (1223major+15581506minor)pagefaults 0swaps

找不到办法，先弃疗。

如果log.makePV没问题的话更新shell环境：

wmRefresh

安装openfoam

cd $WM_PROJECT_DIR
export QT_SELECT=qt5

./Allwmake -j 4 > log.make 2>&1
./Allwmake -j 4 > log.make 2>&1

icoFoam -help

安装hyStrath

基于 MicroNanoFlows/OpenFOAM-2.4.0-MNF 的dsmcfoam+计算。

cd $WM_PROJECT_USER_DIR
git clone https://github.com/hystrath/hyStrath.git --branch master --single-branch && cd hyStrath/

./install.sh 16 2>/dev/null

示例中的monitor还需要：

sudo apt-get install gnuplot-x11

然后

gnuplot monitor
