1 Introduction

This page is dedicated to explaining how to install OpenFOAM OF Version 171.png in openSUSE.


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 openSUSE 12.1

NOTE: These instructions are still being re-written from a pseudo-template page!


Discussion thread where you can ask questions about these steps: Install OpenFOAM-1.7.1 on openSUSE 12.1

Steps:

  1. Switch to root mode (administrator) and install the necessary packages (run one line at a time):
    su -
    zypper install -t pattern devel_C_C++
    #Add the devel:gcc repository, to gain access to GCC 4.5
    zypper ar http://download.opensuse.org/repositories/devel:/gcc/openSUSE_12.1/devel:gcc.repo
    zypper install gcc45 gcc45-c++ cmake libqt4-devel gnuplot openmpi-devel
    exit
  2. Now, since we're trying to minimize the number of packages to be built, the Open-MPI package that is available with openSUSE is going to be chosen. The downside is that this requires that you logout and log back in, for the system to update the environment settings.
    Nonetheless, we can postpone logging out by running:
    source /etc/profile.d/mpi-selector.sh
  3. 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-1.7.1.gtgz?use_mirror=mesh" -O OpenFOAM-1.7.1.tgz
    wget "http://downloads.sourceforge.net/foam/ThirdParty-1.7.1.gtgz?use_mirror=mesh" -O ThirdParty-1.7.1.tgz
     
    tar xzf OpenFOAM-1.7.1.tgz 
    tar xzf ThirdParty-1.7.1.tgz
  4. For building OpenFOAM itself, it depends on whether you have installed the i386 or x86_64 architecture of openSUSE. To check this, run:
    uname -m

    Now, accordingly:

    • For i386:
      #fix the rules' files
      sed -i -e 's/gcc/\$(WM_CC)/' wmake/rules/linuxGcc/c
      sed -i -e 's/g++/\$(WM_CXX)/' wmake/rules/linuxGcc/c++
       
      #here you can change 4 to the number of cores you've got
      source $HOME/OpenFOAM/OpenFOAM-1.7.1/etc/bashrc WM_NCOMPPROCS=4 WM_MPLIB=SYSTEMOPENMPI WM_ARCH_OPTION=32
      export WM_CC='gcc-4.5'
      export WM_CXX='g++-4.5'
       
      echo "source $HOME/OpenFOAM/OpenFOAM-1.7.1/etc/bashrc $FOAM_SETTINGS ; export WM_CC='gcc-4.5'; export WM_CXX='g++-4.5'" >> $HOME/.bashrc
    • For x86_64:
      #fix the rules' files
      sed -i -e 's/gcc/\$(WM_CC)/' wmake/rules/linux64Gcc/c
      sed -i -e 's/g++/\$(WM_CXX)/' wmake/rules/linux64Gcc/c++
       
      #here you can change 4 to the number of cores you've got
      source $HOME/OpenFOAM/OpenFOAM-1.7.1/etc/bashrc WM_NCOMPPROCS=4 WM_MPLIB=SYSTEMOPENMPI
      export WM_CC='gcc-4.5'
      export WM_CXX='g++-4.5'
       
      echo "source $HOME/OpenFOAM/OpenFOAM-1.7.1/etc/bashrc $FOAM_SETTINGS ; export WM_CC='gcc-4.5'; export WM_CXX='g++-4.5'" >> $HOME/.bashrc
  5. 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-1.7.1
     
    # 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
  6. 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
  7. Now, in order to build ParaView 3.10.1 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, which is located at $HOME/OpenFOAM/OpenFOAM-1.7.1/doc/Guides-a4/UserGuide.pdf.
