See the file COPYING in this directory, for a description of the GNU General Public License terms under which you can copy the files.

OpenFOAM is developed and tested on Linux and Mac OS X. Experimental Microsoft Windows port is currently not released - please follow the user forum and annoucements

• Linux

To check your system setup, execute the foamSystemCheck script in the bin/ directory of the OpenFOAM installation. If no problems are reported, proceed to “3. Installation”; otherwise contact your system administrator.

If the user wishes to run OpenFOAM in 32/64-bit mode they should consult the section “Running OpenFOAM in 32-bit mode”.

• Apple Mac OS X

The recommended way of running OpenFOAM on the Mac is to download sparse disk images, mount them on your system and link them into

~/OpenFOAM/OpenFOAM-<VERSION> ~/OpenFOAM/ThirdParty-<VERSION>

Both disk images support case-sensitive file names. If you wish to compile OpenFOAM and Third Party packs from scratch, please create a case-sensitive disk image using the Disk Utility, mount them as above and unpack the sources at appropriate places. The remainder of build instructions is identical to Linux.

Download and unpack the files in the $HOME/OpenFOAM directory as described in: http://www.extend-project.de/

The environment variable settings are contained in files in an etc/ directory in the OpenFOAM release. e.g. in

• $HOME/OpenFOAM/OpenFOAM-<VERSION>/etc/
• where <VERSION> corresponds to the version 1.6-ext etc

1. EITHER, if running bash or ksh (if in doubt type ‘echo $SHELL’), source the etc/bashrc file by adding the following line to the end of your $HOME/.bashrc file:
   • . $HOME/OpenFOAM/OpenFOAM-<VERSION>/etc/bashrc

   Then update the environment variables by sourcing the $HOME/.bashrc file by typing in the terminal:

• . $HOME/.bashrc
  1. OR, if running tcsh or csh, source the etc/cshrc file by adding the following line to the end of your $HOME/.cshrc file:
     • source $HOME/OpenFOAM/OpenFOAM-<VERSION>/etc/cshrc

     Then update the environment variables by sourcing the $HOME/.cshrc file by typing in the terminal:

• source $HOME/.cshrc

OpenFOAM may also be installed in alternative locations. However, the installation directory should be network available (e.g., NFS) if parallel calculations are planned.

The environment variable ‘FOAM_INST_DIR’ can be used to find and source the appropriate resource file. Here is a bash/ksh/sh example:

• export FOAM_INST_DIR=/data/app/OpenFOAM
  • foamDotFile=$FOAM_INST_DIR/OpenFOAM-<VERSION>/etc/bashrc
  • [ -f $foamDotFile ] && . $foamDotFile

  and a csh/tcsh example:

• setenv FOAM_INST_DIR /data/app/OpenFOAM
  • set foamDotFile=$FOAM_INST_DIR/OpenFOAM-<VERSION>/etc/cshrc
  • if ( -f $foamDotFile ) source $foamDotFile

  The value set in ‘$FOAM_INST_DIR’ will be used to locate the remaining parts of the OpenFOAM installation.

A new way of compiling and installing the ThirdParty suite of packages is proposed with OpenFOAM-1.6-ext. Please consult the file ThirdParty/README.ThirdParty a for more information.

If you cannot find an appropriate binary pack for your platform, you can build the complete OpenFOAM from the source-pack. You will first need to compile or obtain a recent version of gcc (we recomend native gcc, coming with your operating system) for your platform, which may be obtained from http://gcc.gnu.org/.

Install the compiler in $WM_PROJECT_INST_DIR/ThirdParty/gcc-<GCC_VERSION>/platforms/$WM_ARCH$WM_COMPILER_ARCH/ and change the gcc version number in $WM_PROJECT_DIR/etc/settings.sh and $WM_PROJECT_DIR/etc/settings.csh appropriately and finally update the environment variables as in section 3.

Now go to the top-level source directory $WM_PROJECT_DIR and execute the top-level build script ‘./Allwmake’. In principle this will build everything, but if problems occur with the build order it may be necessary to update the environment variables and re-execute ‘Allwmake’. If you experience difficulties with building the source-pack, or your platform is not currently supported, please contact <enquiries@wikki.co.uk> to negotiate a support contract and we will do the port and maintain it for future releases.

To check your installation setup, execute the ‘foamInstallationTest’ script (in the bin/ directory of the OpenFOAM installation). If no problems are reported, proceed to getting started with OpenFOAM; otherwise, go back and check you have installed the software correctly and/or contact your system administrator.

Create a project directory within the $HOME/OpenFOAM directory named <USER>-<VERSION> (e.g. ‘jasak-1.6-ext’ for user jasak and OpenFOAM version 1.6-ext) and create a directory named ‘run’ within it, e.g. by typing:

• mkdir -p $HOME/OpenFOAM/${USER}-${WM_PROJECT_VERSION}/run

Copy the ‘tutorial’ examples directory in the OpenFOAM distribution to the ‘run’ directory. If the OpenFOAM environment variables are set correctly, then the following command will be correct:

• cp -r $WM_PROJECT_DIR/tutorials $HOME/OpenFOAM/${USER}-${WM_PROJECT_VERSION}/run

Run the first example case of incompressible laminar flow in a cavity:

• cd $HOME/OpenFOAM/${USER}-${WM_PROJECT_VERSION}/run/tutorials/incompressible/icoFoam/cavity
• blockMesh
• icoFoam
• paraFoam

Please report all bugs and feature requests using our bug tracking system: http://sourceforge.net/apps/mantisbt/openfoam-extend/main_page.php or http://www.extend-project.de/project-final/openfoam-extend-bug-tracker Please also report bugs at the CFD-Online User Forum.

Linux users with a 64-bit machine may install either the OpenFOAM 32-bit version (linux) or the OpenFOAM 64-bit version (linux64), or both. The 64-bit is the default mode on a 64-bit machine. To use an installed 32-bit version, the user must set the environment variable $WM_32 (to anything, e.g. “on”) before sourcing the etc/bashrc (or etc/cshrc) file.
