precompiled

To make OpenFOAM readily available to a larger range of users, OpenCFD works actively with the community surrounding respective Linux distributions to provide precompiled binary installations as system packages. The distributions currently include the following:

System
Ubuntu
openSUSE
CentOS/RedHat/Fedora
Docker

Ubuntu and openSUSE generally receive first attention:

Ubuntu is a very popular distribution with OpenFOAM users.
openSUSE is historically the favoured development platform for OpenCFD Ltd. Since it is an RPM-based system, a well-crafted spec file can also address RedHat-based distributions.

Using the OpenFOAM package

After installation, the OpenFOAM environment can be accessed as described in running.

The Debian (Ubuntu) and RPM packages always include the OpenFOAM shell sessions.
If the openfoam-selector is available at the time of installation, the newly installed packages will be registered with it, allowing use of the openfoam-selector mechanism.

Installation locations

The packages have been designed to allow simultaneous installation of different OpenFOAM versions without file or package-name collisions. This lets users experiment with different OpenFOAM versions, perform back-to-back comparisons, or simply continue with an older version until completion of a particular project.

The system installation prefix /usr/lib/openfoam is used, below which individual versions are located. For example,

/usr/lib/openfoam/openfoam2012/
/usr/lib/openfoam/openfoam2006/
/usr/lib/openfoam/openfoam1912/
...

The OpenFOAM bash session wrapper will be created under /usr/bin. For example,

/usr/bin/openfoam2012
/usr/bin/openfoam2006
/usr/bin/openfoam1912
...

Sub-packages

Satisfying the wishes and requirements of all users is a difficult task. One user (or sysadmin) wants the "only install what I really need" approach [more control, less diskspace]. Another group of users prefers the "just install everything" approach [less control, more diskspace]. We have attempted to strike a reasonable balance between both. For any given base package (e.g., openfoam2012 etc), there are a variant of sub-packages ("only-what-I-need"), but also a default package for the "install-everything" folks.

Here are some common selections:

User Group	What to install	Runtime	Compilation	Tutorials
minimalist	base	yes	no	no
traditional	base-dev (devel)	yes	yes	no
everything	base-default	yes	yes	yes

The longer descriptions:

Sub-Package	Description	Includes
base	OpenFOAM runtime (solver, utils, libraries). Double precision, int32 compilation.	base-common
base-dev (devel)	Development package. Source code headers and wmake build chain. Needed for developing with OpenFOAM, but also if dynamic code compilation is required.	base, base-tools
base-tutorials	Tutorials	base-common
base-default	Meta-package for everything potentially needed	base-dev (devel), base-tutorials.
base-tools	Binaries for OpenFOAM-specific build tools for base-dev (devel).	base-common
base-common	Version information and share files.

Note the package names for Debian (Ubuntu) and RPM packages are intentionally kept very similar, except dev (Debian) vs. develop (RPM) names that follow the respective system conventions.

Package structure (RPM, partly Debian/Ubuntu)

To allow smooth installation and use of multiple OpenFOAM versions on the same system, some installations use a meta-package structure:

Package	Comments
openfoam	The top-level meta package that provides links and requirements for the most recent OpenFOAM release
openfoam-selector	Similar to mpi-selector, used to switch active OpenFOAM versions
openfoam2012	The maintenance version for v2012
openfoam2006	The maintenance version for v2006
openfoam1912	The maintenance version for v1912

The version-specific packages (eg, openfoam2012, openfoam2006, ...) install into distinct directories so that it is possible to have multiple versions available on your systems. The top-level openfoam package registers which of the version-specific packages corresponds to the current release.
