Download OpenFOAM-dev | Ubuntu

Ubuntu Versions

The openfoam-dev pack provides a packaged installation for Ubuntu of the current development line of OpenFOAM, known as OpenFOAM-dev, that contains the source code for the next major release of OpenFOAM. The pack is updated monthly to bring cutting-edge developments to users without them needing to compile source code. Updates can conveniently be installed as part of a standard update within the apt package management tool. The openfoam-dev pack requires the standard paraview package as a dependency, which will installed automatically if it is currently not installed on the system.

The openfoam-dev pack is available for the following versions of Ubuntu Linux for x86 64bit (e.g. Intel and AMD CPUs) and ARM 64bit architectures.

22.04 LTS, codename jammy
24.04 LTS, codename noble

Installation

OpenFOAM-dev 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. To simplify setting up the package repositories, the following instructions add the repositories both to install version releases, e.g. version 13, and to install OpenFOAM-dev.

Open a terminal prompt (Applications → Accessories → Terminal) and copy and paste the following commands in to the terminal prompt. Steps 2-5 should only be required once for a given system.
Install the public key (gpg.key) for the repository to enable package signatures to be verified. (Note: use secure https:// here.)
```
sudo sh -c "wget -O - https://dl.openfoam.org/gpg.key > /etc/apt/trusted.gpg.d/openfoam.asc"
```
If you have added any repository entries for existing dl.openfoam.org previously, remove them by deleting the source list file.
```
sudo rm /etc/apt/sources.list.d/*dl_openfoam_org*list
```
Add both the main and dev repositories at dl.openfoam.org to the list of software repositories for apt to search. (Note: use http:// since https:// may not be supported and is not required since the key provides secure authentication of the package files.)
```
sudo add-apt-repository "http://dl.openfoam.org/ubuntu main dev"
```
For Ubuntu 26.04 LTS (and, in future, newer versions) ONLY: After running the add-apt-repository command, check if a warning is reported which includes:
```
Warning: Skipping acquire of configured file 'main/binary-amd64v3/Packages'...
```
If this warning is present, apply the following command to force apt to use amd64 as the architecture name, not amd64v3.
```
sudo sed -i "s/^$deb$.*$http$/\1 [arch=amd64] \2/" /etc/apt/sources.list.d/*dl_openfoam_org*list
```
Update the apt package list to account for the new download repository location.
```
sudo apt update
```
Install OpenFOAM-dev which also installs paraview as a dependency if it is not already installed.
```
sudo apt -y install openfoam-dev
```

OpenFOAM-dev is now installed in the /opt directory.

Upgrading OpenFOAM-dev

Every week, OpenFOAM-dev is recompiled into a new openfoam-dev pack within the dev repository. The package will be upgraded automatically whenever repository package files are updated and the software is upgraded, e.g. by typing

sudo apt update
sudo apt upgrade

Users can also specifically upgrade openfoam-dev only by the following option:

sudo apt update
sudo apt install --only-upgrade openfoam-dev

User Configuration

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

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
```
At the bottom of that file, add the following line (see Note 1 below) and save the file
```
source /opt/openfoam-dev/etc/bashrc
```
Open a new terminal window (see Note 2 below) and test that the foamRun application, from the OpenFOAM package, is working by typing
```
foamRun -help
```
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 foamRun 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>-dev (e.g. chris-dev for user chris) and create a directory named run within it, e.g. by typing:

mkdir -p $FOAM_RUN

Copy across the backward facing step example and generate the mesh with blockMesh. Run the case with foamRun, using the incompressibleFluid modular solver with steady-state settings, equivalent to the simpleFoam application of old.

cd $FOAM_RUN
cp -r $FOAM_TUTORIALS/incompressibleFluid/pitzDailySteady .
cd pitzDailySteady
blockMesh
foamRun
paraFoam

Refer to the OpenFOAM User Guide to get started.
