Installation/Linux/OpenFOAM-3.0.1/Ubuntu
1 Introduction
This page is dedicated to explaining how to install OpenFOAM in Ubuntu.
If you do not yet feel comfortable using Linux, then perhaps you better first read the page Working with the Shell and train a bit with the shell/terminal environments, so you can have a better perception of the steps shown below.

2 Copy-Paste steps
A few notes before you start copy-pasting:
- Lines that start with # don't have to be copy-pasted. They are just comments to let you know what's going on.
- One wrong character is enough for breaking this guide, so make sure you can read the characters properly or that the installed language system does not break the copied characters!
2.1 Ubuntu 12.04
Here you have at least two choices:
- You can install from source, by either:
- Following the official instructions from here: Download v3.0.1 | Source Pack
- 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.
Steps:
- 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 -
- If the 'sudo' command tells you're not in the sudoers list, then run:
- Update the apt-get cache by running:
apt-get update
- Install the necessary packages:
apt-get install build-essential flex bison zlib1g-dev qt4-dev-tools libqt4-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
Note: It has been reported that the following should also be executed in some cases, so that ParaView and CGAL will build properly:
apt-get install libglu1-mesa-dev libqt4-opengl-dev
- Now exit from the root mode:
exit
- Download and unpack (here you can copy-paste all in single go):
#OpenFOAM downloading and installation cd ~ mkdir OpenFOAM cd OpenFOAM wget "http://downloads.sourceforge.net/foam/OpenFOAM-3.0.1.tgz?use_mirror=mesh" -O OpenFOAM-3.0.1.tgz wget "http://downloads.sourceforge.net/foam/ThirdParty-3.0.1.tgz?use_mirror=mesh" -O ThirdParty-3.0.1.tgz tar -xzf OpenFOAM-3.0.1.tgz tar -xzf ThirdParty-3.0.1.tgz
- 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-3.0.1/bin/mpicc ln -s /usr/bin/mpirun.openmpi OpenFOAM-3.0.1/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-3.0.1/etc/bashrc WM_ARCH_OPTION=32
- 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 2.147×109 cells, faces or points):
source $HOME/OpenFOAM/OpenFOAM-3.0.1/etc/bashrc
- For building with the normal 64-bit integer support (maximum 9.22×1018 cells, faces or points):
source $HOME/OpenFOAM/OpenFOAM-3.0.1/etc/bashrc WM_LABEL_SIZE=64
- For building with the normal 32-bit integer support (maximum 2.147×109 cells, faces or points):
- For i686:
- Save an alias in the personal .bashrc file, simply by running the following command:
echo "alias of301='source \$HOME/OpenFOAM/OpenFOAM-3.0.1/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-3.0.1 shell environment. In other words, whenever you start a new terminal, you should run:of301
For more information on this topic, read section Using aliases to help manage multiple OpenFOAM versions in the page Installation/Working with the Shell. - Ubuntu 12.04 comes with CMake 2.8.7, but ParaView 4.4.0 needs CMake 3.0 or newer series and CGAL also needs CMake. Therefore, we'll need to do a custom build:
cd $WM_THIRD_PARTY_DIR wget "https://raw.github.com/wyldckat/scripts4OpenFOAM3rdParty/master/getCmake" chmod +x getCmake sed -i -e 's=2\.8=3.2=' -e 's=version}\.3=version}.1=' getCmake ./getCmake ./makeCmake > log.makeCM 2>&1 wmSET $FOAM_SETTINGS
- Now let's build the ThirdParty folder, because we need the shell environment to be updated afterwards, for CGAL to be properly picked up for building OpenFOAM:
cd $WM_THIRD_PARTY_DIR # This next command will take a while... somewhere between 5 minutes to 30 minutes. ./Allwmake > log.make 2>&1 #update the shell environment wmSET $FOAM_SETTINGS
- Now, in order to build ParaView 4.4.0, including with the ability to use Python and MPI, several steps are needed:
- For building ParaView with Python and MPI, run:
cd $WM_THIRD_PARTY_DIR #this will take a while... somewhere between 30 minutes to 2 hours or more ./makeParaView4 -python -mpi -python-lib /usr/lib/libpython2.7.so.1.0 > log.makePV 2>&1
- Once the makeParaView4 script is finished running, make sure to check the contents of the file log.makePV and check if there are any errors.
- Finally, update the shell environment:
wmSET $FOAM_SETTINGS
- For building ParaView with Python and MPI, run:
- Now let's build OpenFOAM:
- Go into OpenFOAM's main source folder:
cd $WM_PROJECT_DIR
- 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.
- 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.
- Go into OpenFOAM's main source folder:
- To check if everything went well:
- Check if icoFoam is working, by running this command:
icoFoam -help
which should tell you something like this:
Usage: icoFoam [OPTIONS] options: -case <dir> specify alternate case directory, default is the cwd -noFunctionObjects do not execute functionObjects -parallel run in parallel -roots <(dir1 .. dirN)> slave root directories for distributed running -srcDoc display source code in browser -doc display application documentation in browser -help print the usage
Note: And keep in mind that you need to be careful with the letter case of the command. It's icoFoam, not icoFOAM.
- If the previous command failed to work properly, then edit the file log.make and check if there are any error messages. A few examples on how you can edit this file:
- By using kwrite:
kwrite log.make
- By using gedit:
gedit log.make
- By using nano:
nano log.make
You can then exit by using the key combination Ctrl+X and following any instructions it gives you.
Note: It's the first error message that matters.
- By using kwrite:
- If you don't understand the output, then please compress the log-file log.make and attach the compressed file to a post in the designated thread.
If you do not know how to create a compressed file, then try one of the following examples:- You can compress the file with gzip by running this command:
gzip < log.make > log.make.gz
Then attach the resulting package file named log.make.gz to a post in the designated thread.
- Or you can compress one or more log-files into a tarball package file, by running this command:
tar -czf logs.tar.gz log.*
Then attach the resulting package file named logs.tar.gz to a post in the designated thread.
- You can compress the file with gzip by running this command:
- Instructions on how to further diagnose the issue yourself, have a look at the section Common errors when building OpenFOAM from source code in the page FAQ/Installation and Running.
- Check if icoFoam is working, by running this command:
- Now you can go read the User Guide, where you may have more than one choice:
- Which you can find a local copy of the User Guide by running the following command:
ls -A1 $WM_PROJECT_DIR/doc/Guides*/*UserGuide*.pdf
- You should see two available formats: A4 and US-Letter.
- But if it instead tells you that there is No such file or directory, then the OpenFOAM environment is possibly not properly activated.
- You can also find the more recent OpenFOAM Foundation User Guides online at the following page: official OpenFOAM User Guide - but be careful if you use the version that is too much ahead of the version you are currently using, given that some features have changed overtime.
- Which you can find a local copy of the User Guide by running the following command:

2.2 Ubuntu 14.04
Here you have the following choices:
- You can install the Deb packages, which provide a quick and easy way for having a working installation of OpenFOAM 3.0.1. This is the quickest solution for beginners and instructions are provided here: Download v3.0.1 | Ubuntu
- Note: If are getting an error when trying to install the packages for Ubuntu, then check this FAQ: Why am I not able to install the official OpenFOAM Deb packages on Ubuntu ?
- You can install from source, by either:
- Following the official instructions from here: Download v3.0.1 | Source Pack
- Or by following the detailed step-by-step instructions below...

For more information on this topic, read section Using aliases to help manage multiple OpenFOAM versions in the page Installation/Working with the Shell. - Now let's build the ThirdParty folder, because we need the shell environment to be updated afterwards, for CGAL to be properly picked up for building OpenFOAM:
cd $WM_THIRD_PARTY_DIR #make very certain that the correct Qt version is being used, by running this command: export QT_SELECT=qt4 # This next command will take a while... somewhere between 5 minutes to 30 minutes. ./Allwmake > log.make 2>&1 #update the shell environment wmSET $FOAM_SETTINGS
- Now, in order to build ParaView 4.4.0, including with the ability to use Python and MPI, several steps are needed:
- Make sure you're running in the ThirdParty folder and that the correct Qt version is used:
cd $WM_THIRD_PARTY_DIR export QT_SELECT=qt4

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.
- Since we are going to use CGAL 4.7 that comes with Ubuntu, we are going to configure accordingly by running:
sed -i -e 's/^\(cgal_version=\).*/\1cgal-system/' OpenFOAM-3.0.1/etc/config/CGAL.sh

- For i686:
- Once the makeParaView4 script is finished running, make sure to check the contents of the file log.makePV and check if there are any errors.
- Finally, update the shell environment:
wmSET $FOAM_SETTINGS
- Make sure you're running in the ThirdParty folder and that the correct Qt version is used:
- Now, before we can build OpenFOAM, we need to do a few fixes:
#Go into OpenFOAM's main source folder cd $WM_PROJECT_DIR #Change how the flex version is checked find src applications -name "*.L" -type f | xargs sed -i -e 's=\(YY\_FLEX\_SUBMINOR\_VERSION\)=YY_FLEX_MINOR_VERSION < 6 \&\& \1='
- Now, let's simply create empty folders for the Boost and CGAL installation paths:
mkdir -p $CGAL_ARCH_PATH mkdir -p $BOOST_ARCH_PATH
- Now let's build OpenFOAM:
- Go into OpenFOAM's main source folder and be certain that the correct Qt version is being used:

Discussion thread where you can ask questions about these steps: [OpenFOAM.org] OpenFOAM 3.0.1 in Ubuntu 18.04
Steps:
- 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 -
- If the 'sudo' command tells you're not in the sudoers list, then run:
- Update the apt-get cache by running:
apt-get update
- Install the necessary packages:
apt-get install 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 gcc-5 g++-5
Note: It has been reported that the following should also be executed in some cases, so that ParaView and CGAL will build properly:
apt-get install libglu1-mesa-dev libqt4-opengl-dev
- Now exit from the root mode:
exit
- Download and unpack (here you can copy-paste all in single go):
#OpenFOAM downloading and installation cd ~ mkdir OpenFOAM cd OpenFOAM wget "http://downloads.sourceforge.net/foam/OpenFOAM-3.0.1.tgz?use_mirror=mesh" -O OpenFOAM-3.0.1.tgz wget "http://downloads.sourceforge.net/foam/ThirdParty-3.0.1.tgz?use_mirror=mesh" -O ThirdParty-3.0.1.tgz tar -xzf OpenFOAM-3.0.1.tgz tar -xzf ThirdParty-3.0.1.tgz
- 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-3.0.1/bin/mpicc ln -s /usr/bin/mpirun.openmpi OpenFOAM-3.0.1/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.
- Since we are going to use CGAL 4.7 that comes with Ubuntu, we are going to configure accordingly by running:
sed -i -e 's/^\(cgal_version=\).*/\1cgal-system/' OpenFOAM-3.0.1/etc/config/CGAL.sh
- And we need to use GCC 5, because OpenFOAM 3.0 is not entirely compatible with GCC 7:
sed -i -e 's/gcc/\$(WM_CC)/' OpenFOAM-3.0.1/wmake/rules/linux64Gcc/c sed -i -e 's/g++/\$(WM_CXX)/' OpenFOAM-3.0.1/wmake/rules/linux64Gcc/c++ echo "export WM_CC='gcc-5'" >> OpenFOAM-3.0.1/etc/bashrc echo "export WM_CXX='g++-5'" >> OpenFOAM-3.0.1/etc/bashrc
- 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-3.0.1/etc/bashrc WM_ARCH_OPTION=32
- 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 2.147×109 cells, faces or points):
source $HOME/OpenFOAM/OpenFOAM-3.0.1/etc/bashrc
- For building with the normal 64-bit integer support (maximum 9.22×1018 cells, faces or points):
source $HOME/OpenFOAM/OpenFOAM-3.0.1/etc/bashrc WM_LABEL_SIZE=64
- For building with the normal 32-bit integer support (maximum 2.147×109 cells, faces or points):
- For i686:
- Save an alias in the personal .bashrc file, simply by running the following command:
echo "alias of301='source \$HOME/OpenFOAM/OpenFOAM-3.0.1/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-3.0.1 shell environment. In other words, whenever you start a new terminal, you should run:of301
For more information on this topic, read section Using aliases to help manage multiple OpenFOAM versions in the page Installation/Working with the Shell. - Now, in order to build ParaView 4.4.0, including with the ability to use Python and MPI, several steps are needed:
- Make sure you're running in the ThirdParty folder and that the correct Qt version is used:
cd $WM_THIRD_PARTY_DIR export QT_SELECT=qt4
- 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 ./makeParaView4 -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 ./makeParaView4 -python -mpi -python-lib /usr/lib/x86_64-linux-gnu/libpython2.7.so.1.0 > log.makePV 2>&1
- For i686:
- Once the makeParaView4 script is finished running, make sure to check the contents of the file log.makePV and check if there are any errors.
- Finally, update the shell environment:
wmSET $FOAM_SETTINGS
- Make sure you're running in the ThirdParty folder and that the correct Qt version is used:
- Now, before we can build OpenFOAM, we need to do a few fixes:
#Go into OpenFOAM's main source folder cd $WM_PROJECT_DIR #Change how the flex version is checked find src applications -name "*.L" -type f | xargs sed -i -e 's=\(YY\_FLEX\_SUBMINOR\_VERSION\)=YY_FLEX_MINOR_VERSION < 6 \&\& \1='
- Now, let's simply create empty folders for the Boost and CGAL installation paths:
mkdir -p $CGAL_ARCH_PATH mkdir -p $BOOST_ARCH_PATH
- Now let's build OpenFOAM:
- Go into OpenFOAM's main source folder and be certain that the correct Qt version is being used:
cd $WM_PROJECT_DIR export QT_SELECT=qt4
- 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.
- 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.
- Go into OpenFOAM's main source folder and be certain that the correct Qt version is being used:
- To check if everything went well:
- Check if icoFoam is working, by running this command:
icoFoam -help
which should tell you something like this:
Usage: icoFoam [OPTIONS] options: -case <dir> specify alternate case directory, default is the cwd -noFunctionObjects do not execute functionObjects -parallel run in parallel -roots <(dir1 .. dirN)> slave root directories for distributed running -srcDoc display source code in browser -doc display application documentation in browser -help print the usage
Note: And keep in mind that you need to be careful with the letter case of the command. It's icoFoam, not icoFOAM.
- If the previous command failed to work properly, then edit the file log.make and check if there are any error messages. A few examples on how you can edit this file:
- By using kwrite:
kwrite log.make
- By using gedit:
gedit log.make
- By using nano:
nano log.make
You can then exit by using the key combination Ctrl+X and following any instructions it gives you.
Note: It's the first error message that matters.
- By using kwrite:
- If you don't understand the output, then please compress the log-file log.make and attach the compressed file to a post in the designated thread.
If you do not know how to create a compressed file, then try one of the following examples:- You can compress the file with gzip by running this command:
gzip < log.make > log.make.gz
Then attach the resulting package file named log.make.gz to a post in the designated thread.
- Or you can compress one or more log-files into a tarball package file, by running this command:
tar -czf logs.tar.gz log.*
Then attach the resulting package file named logs.tar.gz to a post in the designated thread.
- You can compress the file with gzip by running this command:
- Instructions on how to further diagnose the issue yourself, have a look at the section Common errors when building OpenFOAM from source code in the page FAQ/Installation and Running.
- Check if icoFoam is working, by running this command:
- Now you can go read the User Guide, where you may have more than one choice:
- Which you can find a local copy of the User Guide by running the following command:
ls -A1 $WM_PROJECT_DIR/doc/Guides*/*UserGuide*.pdf
- You should see two available formats: A4 and US-Letter.
- But if it instead tells you that there is No such file or directory, then the OpenFOAM environment is possibly not properly activated.
- You can also find the more recent OpenFOAM Foundation User Guides online at the following page: official OpenFOAM User Guide - but be careful if you use the version that is too much ahead of the version you are currently using, given that some features have changed overtime.
- Which you can find a local copy of the User Guide by running the following command:
