1 Introduction

This page is dedicated to explaining how to install OpenFOAM OF Version 211.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 10.04

Discussion thread where you can ask questions about these steps: none so far.

Steps:

  1. Switch to root mode (administrator) and install the necessary packages (run one line at a time):
    sudo -s
    #or
    su -
     
    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
     
    exit
  2. 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
  3. 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:
      #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
       
      echo "source $HOME/OpenFOAM/OpenFOAM-2.1.1/etc/bashrc $FOAM_SETTINGS" >> $HOME/.bashrc
    • 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_MPLIB=SYSTEMOPENMPI
       
      echo "source $HOME/OpenFOAM/OpenFOAM-2.1.1/etc/bashrc $FOAM_SETTINGS" >> $HOME/.bashrc
  4. 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
  5. 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
  6. Ubuntu 10.04 comes with CMake 2.8.0, but that version has a bug that makes it impossible to build ParaView 3.12.0. Therefore, we'll need to do a custom build:
    cd $WM_THIRD_PARTY_DIR
    wget "http://www.openfoam.org/mantisbt/file_download.php?file_id=143&type=bug" -O getCmake
    chmod +x getCmake
    ./getCmake
    ./makeCmake
    wmSET $FOAM_SETTINGS
  7. Now, in order to build ParaView 3.12.0 that comes with OpenFOAM:
    cd $WM_THIRD_PARTY_DIR
    ./makeParaView
     
    cd $FOAM_UTILITIES/postProcessing/graphics/PV3Readers 
    wmSET $FOAM_SETTINGS
    ./Allwclean 
    ./Allwmake
  8. Now you can go read the User Guide: official OpenFOAM User Guide
