Start ssh: sudo service ssh start
Stop ssh: service ssh stop

1.3.16. OpenFOAM 4.x

Have to install 32 bit integer support for compatiblility with CFMesh


  • Ubuntu 16.04

Here you have the following choices:

  • Follow the official instructions for building from source code: OpenFOAM Source Repository

  • Or by following the detailed step-by-step instructions below…

Discussion thread where you can ask questions about these steps: No thread available. Please a create a new thread in the forum.


  1. Switch to root mode (administrator), to install the necessary packages:

sudo -s
  • If the ‘sudo’ command tells you’re not in the sudoers list, then run:

su -
  1. Update the apt-get cache by running:

apt-get update
  1. Install the necessary packages:

apt-get install git-core build-essential binutils-dev cmake flex bison zlib1g-dev qt4-dev-tools libqt4-dev libqtwebkit-dev gnuplot \
libreadline-dev libncurses-dev libxt-dev libopenmpi-dev openmpi-bin libboost-system-dev libboost-thread-dev libgmp-dev \
libmpfr-dev python python-dev libcgal-dev

Note: It has been reported that the following should also be executed in some cases, so that ParaView will build properly:

apt-get install libglu1-mesa-dev libqt4-opengl-dev

Now exit from the root mode:

  1. Download and unpack (here you can copy-paste all in single go):

#OpenFOAM downloading and installation
cd ~
mkdir OpenFOAM
cd OpenFOAM
git clone https://github.com/OpenFOAM/OpenFOAM-4.x.git
git clone https://github.com/OpenFOAM/ThirdParty-4.x.git
  1. Optional: Let’s make a few symbolic links that should ensure that the correct global MPI installation is used by this OpenFOAM installation:

ln -s /usr/bin/mpicc.openmpi OpenFOAM-4.x/bin/mpicc
ln -s /usr/bin/mpirun.openmpi OpenFOAM-4.x/bin/mpirun

This way we avoid having problems in case there is more than one MPI toolbox installed in your Ubuntu system, for example if MPICH2 is installed and is the default MPI toolbox.

For building OpenFOAM itself, it depends on whether you have installed the i686 or x86_64 architecture of Ubuntu. To check this, run:

uname -m

Now, accordingly:

For i686:

source $HOME/OpenFOAM/OpenFOAM-4.x/etc/bashrc WM_ARCH_OPTION=32 FOAMY_HEX_MESH=yes
  • For x86_64, it depends on whether you need 64-bit integer support or not:

  • For building with the normal 32-bit integer support (maximum 2.147×10^9 cells, faces or points):

source $HOME/OpenFOAM/OpenFOAM-4.x/etc/bashrc FOAMY_HEX_MESH=yes
  • For building with the normal 64-bit integer support (maximum 9.22×10^18 cells, faces or points):

source $HOME/OpenFOAM/OpenFOAM-4.x/etc/bashrc WM_LABEL_SIZE=64 FOAMY_HEX_MESH=yes
  1. Save an alias in the personal .bashrc file, simply by running the following command:

echo "alias of4x='source \$HOME/OpenFOAM/OpenFOAM-4.x/etc/bashrc $FOAM_SETTINGS'" >> $HOME/.bashrc

Note: This last line means that whenever you start a new terminal window or tab, you should run the alias command associated to the OpenFOAM-4.x shell environment. In other words, whenever you start a new terminal, you should run:


For more information on this topic, read section Using aliases to help manage multiple OpenFOAM versions in the page Installation/Working with the Shell.

  1. Now, in order to build ParaView 5.0.1, including with the ability to use Python and MPI, a few steps are needed:

  1. Make sure you’re running in the ThirdParty folder and that the correct Qt version is used:

export QT_SELECT=qt4
  1. For building ParaView with Python and MPI, it depends on whether you have installed the i686 or x86_64 architecture of Ubuntu. To check this, run:

uname -m

Now, accordingly:

  • For i686:

#this will take a while... somewhere between 30 minutes to 2 hours or more
./makeParaView -python -mpi -python-lib /usr/lib/i386-linux-gnu/libpython2.7.so.1.0 > log.makePV 2>&1
  • For x86_64:

#this will take a while... somewhere between 30 minutes to 2 hours or more
./makeParaView -python -mpi -python-lib /usr/lib/x86_64-linux-gnu/libpython2.7.so.1.0 > log.makePV 2>&1
  1. Now let’s build OpenFOAM:

  1. Go into OpenFOAM’s main source folder and be certain that the correct Qt version is being used:

export QT_SELECT=qt4
  1. This next command will take a while… somewhere between 30 minutes to 3-6 hours:

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

Note: The “4” refers to the number of cores to be used for building in parallel. In addition, the amount of RAM needed for building scales with the number of cores used, something like 1GB of RAM per core; a minimum of 1.5GB is needed for linking the libraries, which is not done in parallel.

  1. Run it a second time for getting a summary of the installation:

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

Note: Technically, the build will stop as soon as the first error is found. Running a second time only makes it easier to sort through between what’s already been built and where the crash occurred.

To check if everything went well: Check if icoFoam is working, by running this command:

icoFoam -help
