Installation/Linux/OpenFOAM-2.3.0/openSUSE
1 Introduction
This page is dedicated to explaining how to install OpenFOAM in openSUSE.
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:
- Lines that start with # don't have to be copy-pasted. They are just comments to let you know what's going on.
- 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 12.3
You can follow either one of these instructions:
- Install the official RPM packages for OpenFOAM 2.3.0: SuSE RPM Pack Installation
- Follow the official instructions for building from source code: Source Pack Installation
- Or follow the instructions below...
Discussion thread where you can ask questions about these steps: none so far.
Steps:
- 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 -
- If the 'sudo' command tells you're not in the sudoers list, then run:
- Install the necessary packages:
zypper install -t pattern devel_C_C++ zypper install cmake libqt4-devel qt4-x11-tools qt4-assistant-adp-devel gnuplot openmpi-devel \ boost-devel gmp-devel mpfr-devel libQtWebKit-devel
- Now exit from the root mode:
exit
- 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
Note: But keep in mind that until you logout, use this command line on every new terminal window/tab! - 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-2.3.0.tgz?use_mirror=mesh" -O OpenFOAM-2.3.0.tgz wget "http://downloads.sourceforge.net/foam/ThirdParty-2.3.0.tgz?use_mirror=mesh" -O ThirdParty-2.3.0.tgz tar -xzf OpenFOAM-2.3.0.tgz tar -xzf ThirdParty-2.3.0.tgz
- 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:
#here you can change 4 to the number of cores you've got source $HOME/OpenFOAM/OpenFOAM-2.3.0/etc/bashrc WM_NCOMPPROCS=4 WM_MPLIB=SYSTEMOPENMPI WM_ARCH_OPTION=32
- For x86_64:
#here you can change 4 to the number of cores you've got source $HOME/OpenFOAM/OpenFOAM-2.3.0/etc/bashrc WM_NCOMPPROCS=4 WM_MPLIB=SYSTEMOPENMPI
- For i386:
-
Save an alias in the personal .bashrc file:
echo "alias of230='source \$HOME/OpenFOAM/OpenFOAM-2.3.0/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 2.3.0 shell environment. In other words, whenever you start a new terminal, you should run:of230
For more information on this topic, read section Using aliases to help manage multiple OpenFOAM versions in the page Installation/Working with the Shell. - 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 # This next command will take a while... somewhere between 5 minutes to 30 minutes. ./Allwmake > make.log 2>&1 #update the shell environment wmSET $FOAM_SETTINGS
- 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 $WM_PROJECT_DIR # 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
- 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: kwrite 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
- Now, in order to build ParaView 4.1.0 that comes with OpenFOAM:
cd $WM_THIRD_PARTY_DIR ./makeParaView4 cd $FOAM_UTILITIES/postProcessing/graphics/PV4Readers wmSET $FOAM_SETTINGS ./Allwclean ./Allwmake
- Now you can go read the User Guide: official OpenFOAM User Guide

2.2 openSUSE 13.1
WARNING: THESE INSTRUCTIONS ARE STILL BEING TESTED/WRITTEN.
The steps meant for openSUSE 12.3 work as intended for 13.1.
Discussion thread where you can ask questions about these steps for openSUSE 13.1: none so far.
