1 Introduction

This page is dedicated to explaining how to install OpenFOAM OF Version 211.png in:

  • Community ENTerprise Operating System, aka CentOS.
  • Red Hat Enterprise Linux, aka RHEL.
  • Scientific Linux, aka SL.

In theory, all of the above follow the same versioning. Therefore, at the time this page was first written, RHEL, CentOS and SL were all at version 6.3.

Both SL and CentOS derive from RHEL, but CentFOAM is what inspired this page. Therefore, before even trying to follow the instructions on this page, try first CentFOAM.

Last but not least, RHEL uses Fedora as their bleeding edge Linux Distribution, where they test new features. This leads to very close similarities between them, e.g. RHEL 6.3 is very similar to Fedora 14; which means that whatever you can build on Fedora 14, you should also be able to build on RHEL 6.3!

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 CentOS 5.1

Note: this was tested with the normal 7 CD-pack of CentOS 5.1 x86_64, installed in a virtual machine.

Discussion thread where you can ask questions about these steps: problem in installation in OpenFOAM-2.1.x on Red Hat

Steps:

  1. Switch to root mode (administrator) and install the necessary packages (run one line at a time):
    su -
    yum groupinstall 'Development Tools' 
    yum install gcc44 gcc44-c++ openmpi openmpi-devel zlib-devel
     
    #these are needed for Qt and ParaView
    yum install libXt-devel libXext-devel libXrender-devel
     
    #This one is useful, but not crucial
    yum upgrade
  2. Continue in step #2 in the section CentOS 5.8.


2.2 CentOS 5.8

Note: this was tested with the normal DVD of CentOS 5.8, installed in a virtual machine.

Discussion thread where you can ask questions about these steps: Installing OpenFOAM 2.1.1 on CentOS 5.x

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. Install the necessary packages:
    yum groupinstall 'Development Tools' 
    yum install gcc44 gcc44-c++ openmpi openmpi-devel zlib-devel
     
    #This one is useful, but not crucial
    yum upgrade
  3. For building OpenFOAM itself and using the dedicated Open-MPI version, it depends on whether you have installed the i386 or x86_64 architecture of CentOS/SL/RHEL. To check this, run:
    uname -m

    Now, accordingly:

    • For i386:
      #forcefully load Open-MPI into the environment
      mpi-selector --system --set openmpi-1.4-gcc-i386
    • For x86_64:
      #forcefully load Open-MPI into the environment
      mpi-selector --system --set openmpi-1.4-gcc-x86_64
  4. Now exit from the root mode:
    exit
  5. Start a new terminal. This is because you'll need a fully refreshed shell.
  6. 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-2.1.1.tgz?use_mirror=mesh" -O OpenFOAM-2.1.1.tgz
    wget "http://downloads.sourceforge.net/foam/ThirdParty-2.1.1.tgz?use_mirror=mesh" -O ThirdParty-2.1.1.tgz
     
    tar -xzf OpenFOAM-2.1.1.tgz 
    tar -xzf ThirdParty-2.1.1.tgz
  7. According to the previously determined architecture:
    • For i386:
      #here you can change 4 to the number of cores you've got
      source $HOME/OpenFOAM/OpenFOAM-2.1.1/etc/bashrc WM_NCOMPPROCS=4 WM_COMPILER=Gcc44 WM_MPLIB=SYSTEMOPENMPI WM_ARCH_OPTION=32
      export WM_CC='gcc44'
      export WM_CXX='g++44'
       
      sed -i -e 's=gcc=$(WM_CC)=' OpenFOAM-2.1.1/wmake/rules/linuxGcc44/c
      sed -i -e 's=g++=$(WM_CXX)=' OpenFOAM-2.1.1/wmake/rules/linuxGcc44/c++
    • For x86_64:
      #here you can change 4 to the number of cores you've got
      source $HOME/OpenFOAM/OpenFOAM-2.1.1/etc/bashrc WM_NCOMPPROCS=4 WM_COMPILER=Gcc44 WM_MPLIB=SYSTEMOPENMPI
      export WM_CC='gcc44'
      export WM_CXX='g++44'
       
      sed -i -e 's=gcc=$(WM_CC)=' OpenFOAM-2.1.1/wmake/rules/linux64Gcc44/c
      sed -i -e 's=g++=$(WM_CXX)=' OpenFOAM-2.1.1/wmake/rules/linux64Gcc44/c++
  8. Save an alias in the personal .bashrc file:
    FULL_SETTINGS="$FOAM_SETTINGS; export WM_CC=gcc44; export WM_CXX=g++44"
    echo "alias of211='source \$HOME/OpenFOAM/OpenFOAM-2.1.1/etc/bashrc ${FULL_SETTINGS}'" >> $HOME/.bashrc
    unset FULL_SETTINGS
    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 2.1.1 shell environment. In other words, whenever you start a new terminal, you should run:
    of211
    
    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 OpenFOAM:
    (Warning: this may take somewhere from 30 minutes to 6 hours, depending on your machine.)
    #Go into OpenFOAM's main source folder
    cd OpenFOAM-2.1.1
     
    # This next command will take a while... somewhere between 30 minutes to 3-6 hours.
    ./Allwmake > make.log 2>&1
     
    #Run it a second time for getting a summary of the installation
    ./Allwmake > make.log 2>&1
  10. To check if everything went well:
    #Check if icoFoam is working
    icoFoam -help
     
    #Edit the file "make.log" and check if there are any error messages
    #Example:
    gedit make.log
     
    #Create a tarball in case you've seen any errors (it's the first error that matters)
    #or if you don't understand the output
    #and attach the file "make.log.tar.gz" to a post in the designated thread
    tar -czf make.log.tar.gz make.log
  11. CentOS 5.8 comes with CMake 2.6.4, but ParaView 3.12.0 needs a one of the versions from the more recent CMake 2.8.x series. 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
    ./getCmake
    ./makeCmake
    wmSET $FOAM_SETTINGS
  12. CentOS 5.8 comes with Qt 4.2.1, but ParaView 3.12.0 needs at least 4.5, with 4.6 as recommended. Therefore, we'll need to do a custom build:
    cd $WM_THIRD_PARTY_DIR
    wget "https://raw.github.com/wyldckat/scripts4OpenFOAM3rdParty/master/getQt"
    chmod +x getQt
    ./getQt
     
    #fix the defaults for Qt not to use gcc or g++ by default
    sed -i -e 's/= gcc/= gcc44/' qt-everywhere-opensource-src-4.6.4/mkspecs/common/g++.conf
    sed -i -e 's/= g++/= g++44/' qt-everywhere-opensource-src-4.6.4/mkspecs/common/g++.conf
     
    ./makeQt 4.6.4 > mkqt.log 2>&1
  13. Now, in order to build ParaView 3.12.0 that comes with OpenFOAM, along with the Qt version recently built:
    cd $WM_THIRD_PARTY_DIR
    ./makeParaView -qmake $WM_THIRD_PARTY_DIR/platforms/$WM_ARCH$WM_COMPILER/qt-4.6.4/bin/qmake PARAVIEW_INSTALL_THIRD_PARTY_LIBRARIES:BOOL=ON
     
    cd $FOAM_UTILITIES/postProcessing/graphics/PV3Readers 
    wmSET $FOAM_SETTINGS
    export PATH=$WM_THIRD_PARTY_DIR/platforms/$WM_ARCH$WM_COMPILER/qt-4.6.4/bin:$PATH
    ./Allwclean 
    ./Allwmake
  14. Now you can go read the User Guide: official OpenFOAM User Guide


Reminder: Whenever you start a new terminal window or tab, you should run the alias command associated to the OpenFOAM 2.1.1 shell environment. In other words, run the following command whenever you start a new terminal:
of211

Discussion thread where you can ask questions about these steps: Installing OpenFOAM 2.1.1 on CentOS 5.x


2.3 CentOS 6.3

Note: this was tested with the LiveDVD's of CentOS 6.3, installed in a virtual machine.

Discussion thread where you can ask questions about these steps: OpenFOAM installation in SL 6.3 (guide req)

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. Install the necessary packages:
    yum groupinstall 'Development Tools' 
    yum install openmpi openmpi-devel qt-devel qt-webkit-devel zlib-devel
     
    #This one is useful, but not crucial
    yum upgrade
  3. Now exit from the root mode:
    exit
  4. Start a new terminal. This is because you'll need a fully refreshed shell.
  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/foam/OpenFOAM-2.1.1.tgz?use_mirror=mesh" -O OpenFOAM-2.1.1.tgz
    wget "http://downloads.sourceforge.net/foam/ThirdParty-2.1.1.tgz?use_mirror=mesh" -O ThirdParty-2.1.1.tgz
     
    tar -xzf OpenFOAM-2.1.1.tgz 
    tar -xzf ThirdParty-2.1.1.tgz
  6. For building OpenFOAM itself, it depends on whether you have installed the i386 or x86_64 architecture of CentOS/SL/RHEL. To check this, run:
    uname -m

    Now, accordingly:

    • For i386:
      #forcefully load Open-MPI into the environment
      module load openmpi-i386
       
      #here you can change 4 to the number of cores you've got
      source $HOME/OpenFOAM/OpenFOAM-2.1.1/etc/bashrc WM_NCOMPPROCS=4 WM_MPLIB=SYSTEMOPENMPI WM_ARCH_OPTION=32

      Also, save an alias in the personal .bashrc file:

      echo "alias of211='module load openmpi-i386; source \$HOME/OpenFOAM/OpenFOAM-2.1.1/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 2.1.1 shell environment. In other words, whenever you start a new terminal, you should run:
      of211
      
      For more information on this topic, read section Using aliases to help manage multiple OpenFOAM versions in the page Installation/Working with the Shell.
    • For x86_64:
      #forcefully load Open-MPI into the environment
      module load openmpi-x86_64       
       
      #here you can change 4 to the number of cores you've got
      source $HOME/OpenFOAM/OpenFOAM-2.1.1/etc/bashrc WM_NCOMPPROCS=4 WM_MPLIB=SYSTEMOPENMPI

      Also, save an alias in the personal .bashrc file:

      echo "alias of211='module load openmpi-x86_64; source \$HOME/OpenFOAM/OpenFOAM-2.1.1/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 2.1.1 shell environment. In other words, whenever you start a new terminal, you should run:

  7. Now let's build OpenFOAM:
    (Warning: this may take somewhere from 30 minutes to 6 hours, depending on your machine.)
    #Go into OpenFOAM's main source folder
    cd OpenFOAM-2.1.1
     
    # This next command will take a while... somewhere between 30 minutes to 3-6 hours.
    ./Allwmake > make.log 2>&1
     
    #Run it a second time for getting a summary of the installation
    ./Allwmake > make.log 2>&1
  8. To check if everything went well:
    #Check if icoFoam is working
    icoFoam -help
     
    #Edit the file "make.log" and check if there are any error messages
    #Example:
    gedit make.log
     
    #Create a tarball in case you've seen any errors (it's the first error that matters)
    #or if you don't understand the output
    #and attach the file "make.log.tar.gz" to a post in the designated thread
    tar -czf make.log.tar.gz make.log
  9. CentOS 6.3 comes with CMake 2.6.4, but ParaView 3.12.0 needs a one of the versions from the more recent CMake 2.8.x series. 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
    ./getCmake
    ./makeCmake
    wmSET $FOAM_SETTINGS
  10. Now, in order to build ParaView 3.12.0 that comes with OpenFOAM:
    cd $WM_THIRD_PARTY_DIR
    ./makeParaView -qmake $(which qmake-qt4)
     
    cd $FOAM_UTILITIES/postProcessing/graphics/PV3Readers 
    wmSET $FOAM_SETTINGS
    ./Allwclean 
    ./Allwmake
  11. Now you can go read the User Guide: official OpenFOAM User Guide
