Ubuntu Deb Pack Installation

Ubuntu Deb Pack Installation

Version 2.3.1, released 10/12/14

Ubuntu Versions

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

  • 14.04 LTS, codename trusty
  • 14.10, codename utopic

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.org/download/ubuntu $VERS main > /etc/apt/sources.list.d/openfoam.list"
    • Note 1: Line 1 stores the version name of your Ubuntu distribution (e.g. raring) under $VERS, which is used in line 2
    • Note 2: This only needs to be done once for a given system
  2. Update the apt package list to account for the new download repository location

    sudo apt-get update
  3. Install OpenFOAM (231 in the name refers to version 2.3.1):

    sudo apt-get install openfoam231
  4. Install Paraview (410 in the name refers to version 4.1.0):

    sudo apt-get install paraviewopenfoam410

OpenFOAM-2.3.1 is now installed in the /opt directory (along with and Paraview-4.1.0)

Installation Problems

  • Networking must be enabled in order to be able to install software packages in Ubuntu. Installation failure due to networking problems usually results in an error message that reports failures in fetching archives and ends with a line like the following:

    E: Unable to fetch some archives...
  • A few users have encountered an error message similar to the following during installation (step 3)

    Some packages could not be installed. This may mean that you
    have requested an impossible situation...
    ...
    The following information may help to resolve the situation:

    The following packages have unmet dependencies: openfoam231 :
    Depends: csh but it is not installable
    Depends: libopenmpi1.3 but it is not installable...

    The most likely cause of this error message is that the universe repositories are not enabled. To enable them, type the following in a terminal window:

    sudo apt-add-repository universe
    sudo apt-get update
  • If MPICH is installed on the system, then during user configuration (below), the following error message might occur when sourcing the etc/bashrc file in the OpenFOAM installation:

    gcc: error: unrecognized command line option '--showme:link'
    The user can check whether MPICH is installed by typing the following:

    sudo update-alternatives --list mpi
    which returns /usr/mpich/include if MPICH is installed. This error is caused when the default mpicc is MPICH, rather than OpenMPI. The simplest way to fix the problem is to set mpicc to OpenMPI is by running the following command in a terminal prompt:

    sudo update-alternatives --set mpi /usr/lib/openmpi/include
  • The .deb files for different versions of Ubuntu supplied can be downloaded directly from the following locations:
      http://www.openfoam.org/download/ubuntu/dists/trusty/main/binary-i386/openfoam231_0-1_i386.deb
      http://www.openfoam.org/download/ubuntu/dists/trusty/main/binary-i386/paraviewopenfoam410_0-1_i386.deb
      http://www.openfoam.org/download/ubuntu/dists/trusty/main/binary-amd64/openfoam231_0-1_amd64.deb

      http://www.openfoam.org/download/ubuntu/dists/utopic/main/binary-amd64/paraviewopenfoam410_0-1_amd64.deb

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/openfoam231/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>-2.3.1 (e.g. chris-2.3.1 for user chris and OpenFOAM version 2.3.1) 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.
