1 Installation under gentoo linux

Valid versions: OF version 15.png

You should have layman installed, if not just emerge it. After installing layman successfully, you have to add the sunrise overlay.

 
layman -a sunrise

Then you can install the openfoam meta package and paraview easily.

 
emerge openfoam-meta paraview

In order to get OpenFOAM running, add the following line to your ~/.bashrc

 alias startOF15="source /usr/lib/OpenFOAM/OpenFOAM-1.5/etc/bashrc"

And each time you want to use OpenFOAM just type "startOF15" in the active terminal.

2 Installation under debian or ubuntu linux

Valid versions: OF version 15.png

2.1 Ubuntu Intrepid 8.10

You have to add the following line to /etc/apt/sources.list either with your preferred text editor or package manager.

 deb http://ppa.launchpad.net/cae-team/ppa/ubuntu intrepid main

The you have to update your repository list, for example with

 
sudo apt-get update

After that you can install openfoam and paraview just by typing

 
sudo apt-get install openfoam paraview

In order to get OpenFOAM running, add the following line to your ~/.bashrc

 alias startOF15="source /usr/lib/OpenFOAM-1.5/etc/bashrc"

And each time you want to use OpenFOAM just type "startOF15" in the active terminal.

2.2 Debian or other Ubuntu versions

You can check, if you can install the openfoam binaries, like with Ubuntu Intrepid 8.10. If this not applies, e.g. due to dependency problems, then you have to add the following line to the /etc/apt/sources.list

 deb-src http://ppa.launchpad.net/cae-team/ppa/ubuntu intrepid main


Update you repository list

 
sudo apt-get update

After adding this line, you have to compile the debian source package of openfoam and/or paraview at your own by typing

 
apt-get -b source openfoam

and/or

 
apt-get -b source parafoam

For further information about debian source packages, follow these guidlines.

In order to get OpenFOAM running, add the following line to your ~/.bashrc

 alias startOF15="source /usr/lib/OpenFOAM-1.5/etc/bashrc"

And each time you want to use OpenFOAM just type "startOF15" in the active terminal.

3 Manual Installation

Valid versions: OF version 14.png

This is a step-by-step installation guide to OpenFOAM on 32bit machines. It is highly focused on Linux-newbies, thus many steps might look superfluous on more experienced users. The character ">" is used to signal that what follows on that specific line is to be typed in a command line.

- Make a directory for your OpenFOAM installation by typing:

 > mkdir $HOME/OpenFOAM
 > cd $HOME/OpenFOAM
 > mkdir linux

- Download the following six archives from the opencfd-homepage to the $HOME/OpenFOAM directory:

 > OpenFOAM-1.4.1.General.gtgz
 > OpenFOAM-1.4.1.linuxGccDOpt.gtgz
 > OpenFOAM-1.4.1.linuxGccSOpt.gtgz
 > gcc-4.2.1.linux.tgz
 > j2sdk1.4.2_05.linux.tgz
 > paraview-2.4.4.linux.tgz

- Open a terminal and type:

 > ls /usr/include/features.h
 a) EITHER "/usr/include/features.h" is written to screen. Do not do any further.
 b) OR "cannot access /usr/include/features.h: No such file or directory" 
    is written to screen. You need the build essentials to compile your own 
    boundary conditions, thus type the following in a terminal:
    > aptitude install build-essential gcc

- Unpack the archives by typing the following command:

 > cd $HOME/OpenFOAM
 > tar -xzf OpenFOAM-1.4.1.General.gtgz
 > tar -xzf OpenFOAM-1.4.1.linuxGCCDPOpt.gtgz
 > tar -xzf OpenFOAM-1.4.1.linuxGCCSPOpt.gtgz
 > tar -xzf gcc-4.2.1.linux.tgz linux/
 > mv *.tgz linux/.
 > cd linux
 > tar -xzf gcc-4.2.1.linux.tgz
 > tar -xzf j2sdk1.4.2_05.linux.tgz
 > tar -xzf paraview-2.4.4.linux.tgz

- You need to set some environmental variables to be able to run OpenFOAM. This is done in the following way:

 a) EITHER, if running bash or ksh (if in doubt type 'echo $SHELL'), do the 
    following:
    > nano $HOME/.bashrc (this open a text-editor in your command window)
    In the end of the file you type:
    . $HOME/OpenFOAM/OpenFOAM-1.4.1/.OpenFOAM-1.4.1/bashrc
    Press 'CTRL-X' to quit nano and agree to save changes.
 a) OR, if running tcsh or csh (if in doubt type 'echo $SHELL'), do the 
    following:
    > nano $HOME/.cshrc (this open a text-editor in your command window)
    In the end of the file you type:
    source $HOME/OpenFOAM/OpenFOAM-1.4.1/.OpenFOAM-1.4.1/cshrc
    Press 'CTRL-X' to quit nano and agree to save changes.

- Open a new command-window. This will read $HOME/.bashrc and set all the necessary environmental variables. To check the installation do:

 > cd ~/OpenFOAM/OpenFOAM-1.4.1/bin
 > sh foamInstallationTest

- On single-machine setups, the installation test will probably produce a report which looks like this in the last couple of lines:

 FATAL ERROR: No remote shell available.
              Foam1.4.1 enviroment requires either ssh and/or rsh.
              Contact your system administrator.


 -------------------------------------------------------------------------------

 The system test has evoked 1 fatal error(s).

 Critical systems ok.

 Review the output for warning messages and consult 
 the installation guide for trouble shooting.
 ==============================================================================
 This fatal error is due the test_rsh and test_ssh critiria, though they are 
 irrelevant on single-machine installations, i.e. only relevant for parallel-
 processing on multiple machine.

- To setup the a working directory, follow step 6 in the ~/OpenFOAM/OpenFOAM-1.4.1/README file.

- You are now ready to begin working with OpenFOAM.

- Have fun:)
