| − | 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:

| + | |
| − | | + | |
| − | This fatal error is due the test_rsh and test_ssh critiria, though they are

| − | - 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.
