1 Introduction

This page is dedicated to explaining how to install OpenFOAM OF Version 222.png in Fedora.

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 Fedora 18

Here you have at least two choices:

  • You can install the RPM packages, which provide a quick and easy way for having a working installation of OpenFOAM 2.2.2. This is the quickest solution for beginners and instructions are provided here: Download v2.2.2 | Fedora
  • 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. Install the necessary packages:
    yum groupinstall 'Development Tools' 
    yum install openmpi openmpi-devel qt-devel qt-webkit-devel zlib-devel cmake wget
  3. Now exit from the root mode:
    exit
  4. 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-2.2.2.tgz?use_mirror=mesh" -O OpenFOAM-2.2.2.tgz
    wget "http://downloads.sourceforge.net/foam/ThirdParty-2.2.2.tgz?use_mirror=mesh" -O ThirdParty-2.2.2.tgz
     
    tar -xzf OpenFOAM-2.2.2.tgz 
    tar -xzf ThirdParty-2.2.2.tgz
  5. For building OpenFOAM itself, it depends on whether you have installed the i386 or x86_64 architecture of Fedora. To check this, run:
    uname -m

    Now, accordingly:

    • For i386:
      #forcefully load Open-MPI into the environment
      module load mpi/openmpi-i386
       
      #here you can change 4 to the number of cores you've got
      source $HOME/OpenFOAM/OpenFOAM-2.2.2/etc/bashrc WM_NCOMPPROCS=4 WM_MPLIB=SYSTEMOPENMPI WM_ARCH_OPTION=32

      Also, save an alias in the personal .bashrc file, simply by running the following command:

      echo "alias of222='module load mpi/openmpi-i386; source \$HOME/OpenFOAM/OpenFOAM-2.2.2/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 2.2.2 shell environment. In other words, whenever you start a new terminal, you should run:
      of222
      
      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 mpi/openmpi-x86_64       
       
      #here you can change 4 to the number of cores you've got
      source $HOME/OpenFOAM/OpenFOAM-2.2.2/etc/bashrc WM_NCOMPPROCS=4 WM_MPLIB=SYSTEMOPENMPI

      Also, save an alias in the personal .bashrc file, simply by running the following command:

      echo "alias of222='module load mpi/openmpi-x86_64; source \$HOME/OpenFOAM/OpenFOAM-2.2.2/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 2.2.2 shell environment. In other words, whenever you start a new terminal, you should run:
      of222
      
      For more information on this topic, read section Using aliases to help manage multiple OpenFOAM versions in the page Installation/Working with the Shell.
  6. 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-2.2.2
     
    # This next command will take a while... somewhere between 30 minutes to 3-6 hours.
    ./Allwmake > log.make 2>&1
     
    #Run it a second time for getting a summary of the installation
    ./Allwmake > log.make 2>&1
  7. 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.
  8. 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
  9. 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 the OpenFOAM environment is possibly not properly activated.
    2. 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.


Reminder: Whenever you start a new terminal window or tab, you should run the alias command associated to the OpenFOAM 2.2.2 shell environment. In other words, run the following command whenever you start a new terminal:
of222

2.2 Fedora 20

Here you have at least two choices:

  • You can install the RPM packages, which provide a quick and easy way for having a working installation of OpenFOAM 2.2.2. This is the quickest solution for beginners and instructions are provided here: Download v2.2.2 | Fedora
    • ... from which you probably have to follow the instructions meant for Fedora 19.
  • You can install from source, by either:

    yum groupinstall 'C Development Tools and Libraries'
    yum install openmpi openmpi-devel qt-devel qt-webkit-devel zlib-devel cmake wget
  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-2.2.2.tgz?use_mirror=mesh" -O OpenFOAM-2.2.2.tgz
