1 Introduction

This page is dedicated to explaining how to install OpenFOAM+ OF Version 30plus.png 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:

  1. Lines that start with # don't have to be copy-pasted. They are just comments to let you know what's going on.
  2. 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 14.04

Here you have the following choices:

  • You can install from source, by either:


Discussion thread where you can ask questions about these steps: OpenFOAM plus [Ubuntu 14.04] installation going bizzard

Steps:

  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 -
  2. Update the apt-get cache by running:
    apt-get update
  3. 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

    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
  4. Now exit from the root mode:
    exit
  5. 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/openfoamplus/files/OpenFOAM-v3.0%2B.tgz?use_mirror=mesh" -O OpenFOAM-v3.0+.tgz
    wget "http://downloads.sourceforge.net/openfoamplus/files/ThirdParty-v3.0%2B.tgz?use_mirror=mesh" -O ThirdParty-v3.0+.tgz
     
    tar -xzf OpenFOAM-v3.0+.tgz
    tar -xzf ThirdParty-v3.0+.tgz
  6. 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-v3.0+/bin/mpicc
    ln -s /usr/bin/mpirun.openmpi OpenFOAM-v3.0+/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.

  7. 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-v3.0+/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-v3.0+/etc/bashrc
      • For building with the normal 64-bit integer support (maximum 9.22×1018 cells, faces or points):
        source $HOME/OpenFOAM/OpenFOAM-v3.0+/etc/bashrc WM_LABEL_SIZE=64
  8. Save an alias in the personal .bashrc file, simply by running the following command:
    echo "alias of30+='source \$HOME/OpenFOAM/OpenFOAM-v3.0+/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+ shell environment. In other words, whenever you start a new terminal, you should run:
    of30+
    
    For more information on this topic, read section Using aliases to help manage multiple OpenFOAM versions in the page Installation/Working with the Shell.
  9. 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
  10. Now, in order to build ParaView 4.4.0, including with the ability to use Python and MPI, several steps are needed:
    1. 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
    2. 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
    3. 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.
    4. Finally, update the shell environment:
      wmSET $FOAM_SETTINGS
  11. Now let's build OpenFOAM+:
    1. 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
    2. 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.

    3. 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.

  12. To check if everything went well:
    1. 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.

    2. 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.

    3. 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.

    4. 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.
  13. Now you can go read the User Guide, where you may have more than one choice:
    1. 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 either the OpenFOAM environment is possibly not properly activated, or the version no longer provides PDF documentation with the installation.
    2. You can find the more recent OpenFOAM Documentation online that is provided by ESI-OpenCFD at the following page: OpenFOAM® Documentation - but be careful that if your version is older than the current release, then the instructions on the documentation may not work, because the documentation is updated with each new release.
      That said, if you need to upgrade custom code that was built with the older versions, they do provide instructions on what changed in the source code, that you will need to adapt to.


Reminder: Whenever you start a new terminal window or tab, you should run the alias command associated to the OpenFOAM+ 3.0+ shell environment. In other words, run the following command whenever you start a new terminal:
of30+

2.2 Ubuntu 16.04

Here you have the following choices:

  • You can install from source, by either:


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

Steps:

  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 -
  2. Update the apt-get cache by running:
    apt-get update
  3. 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 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
  4. Now exit from the root mode:
    exit
  5. 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/openfoamplus/files/OpenFOAM-v3.0%2B.tgz?use_mirror=mesh" -O OpenFOAM-v3.0+.tgz
    wget "http://downloads.sourceforge.net/openfoamplus/files/ThirdParty-v3.0%2B.tgz?use_mirror=mesh" -O ThirdParty-v3.0+.tgz
     
    tar -xzf OpenFOAM-v3.0+.tgz
    tar -xzf ThirdParty-v3.0+.tgz
  6. 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-v3.0+/bin/mpicc
    ln -s /usr/bin/mpirun.openmpi OpenFOAM-v3.0+/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.

  7. 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-v3.0+/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-v3.0+/etc/bashrc
      • For building with the normal 64-bit integer support (maximum 9.22×1018 cells, faces or points):
        source $HOME/OpenFOAM/OpenFOAM-v3.0+/etc/bashrc WM_LABEL_SIZE=64
  8. Save an alias in the personal .bashrc file, simply by running the following command:
    echo "alias of30+='source \$HOME/OpenFOAM/OpenFOAM-v3.0+/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+ v3.0+ shell environment. In other words, whenever you start a new terminal, you should run:
    of30+
    
    For more information on this topic, read section Using aliases to help manage multiple OpenFOAM versions in the page Installation/Working with the Shell.
  9. Now, before we can build OpenFOAM+, we need to fix how Flex version is identified:
    cd $WM_PROJECT_DIR
    find src applications -name "*.L" -type f | xargs sed -i -e 's=\(YY\_FLEX\_SUBMINOR\_VERSION\)=YY_FLEX_MINOR_VERSION < 6 \&\& \1='
  10. 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
    wmREFRESH
  11. Now, in order to build ParaView 5.0.1, including with the ability to use Python and MPI, several steps are needed:
    1. 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
    2. 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
    3. Once the makeParaView script is finished running, make sure to check the contents of the file log.makePV and check if there are any errors.
    4. Finally, update the shell environment:
      wmREFRESH
  12. Now let's build OpenFOAM+:
    1. 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
    2. 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.

    3. 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.

  13. To check if everything went well:
    1. 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.

    2. 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.

    3. 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.

    4. 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.
  14. Now you can go read the User Guide, where you may have more than one choice:
