Ubuntu Deb Pack Installation

Version 2.0.1, released 04/08/11

Ubuntu Versions

OpenFOAM and Paraview are currently available for the following versions of Ubuntu:

Installation

OpenFOAM and Paraview can be simply installed using the apt package management tool. The user will need to provide superuser password authentication when executing the following commands with sudo

  1. In a terminal window, add OpenFOAM to the list of repository locations for apt to search, by copying and pasting the following in a terminal prompt (Applications -> Accessories -> Terminal).

    VERS=`lsb_release -cs`
    sudo sh -c "echo deb http://www.openfoam.com/download/ubuntu $VERS main > /etc/apt/sources.list.d/openfoam.list"
  2. Update the apt package list to account for the new download repository location

    sudo apt-get update
  3. Install OpenFOAM (201 in the name refers to version 2.0.1):

    sudo apt-get install openfoam201
  4. Install Paraview (3101 in the name refers to version 3.10.1):

    sudo apt-get install paraviewopenfoam3101

OpenFOAM-2.0.1 and Paraview-3.10.1 are now installed in the /opt directory.

User Configuration

In order to use the installed OpenFOAM package, complete the following

  1. Open the .bashrc file in the user’s home directory in an editor, e.g. by typing in a terminal window (note the dot)

    gedit ~/.bashrc
  2. At the bottom of that file, add the following line (see Note 1) and save the file

    source /opt/openfoam201/etc/bashrc
  3. Open a new terminal window (see Note 2) and test that the icoFoam application, from the OpenFOAM package, is working by typing

    icoFoam -help
  4. A “Usage” message should appear. Your installation and user configuration is complete.

Note 1: If a similar line has already been added to the user’s .bashrc file, e.g. for a previous version of OpenFOAM, then the line should be deleted or, alternatively, commented out by inserting a # at the beginning of the line.
Note 2: If a user wishes to execute icoFoam in the same terminal window, they must first register the change to the .bashrc file by typing at the terminal prompt (note the dots):  source $HOME/.bashrc

Getting Started

Create a project directory within the $HOME/OpenFOAM directory named <USER>-2.0.1 (e.g. chris-2.0.1 for user chris and OpenFOAM version 2.0.1) and create a directory named run within it, e.g. by typing:

mkdir -p $FOAM_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 $FOAM_TUTORIALS $FOAM_RUN
Run the first example case of incompressible laminar flow in a cavity:

cd $FOAM_RUN/tutorials/incompressible/icoFoam/cavity
blockMesh
icoFoam
paraFoam
Refer to the OpenFOAM User Guide to get started.
