openfoam selector · Wiki · Development / openfoam

The openfoam-selector package is used to register which OpenFOAM packages are installed on the system and allows the user or system administrator select one of them.

Depending on your packaging system (or system administrator), openfoam-selector and openfoam-selector-menu commands may be available to define the preferred OpenFOAM version for the login shell.

To display which versions are installed:

$ openfoam-selector --list

openfoam
openfoam1812
openfoam1906
openfoam1912
openfoam2006

To set a particular version

$ openfoam-selector --set openfoam2006

To query the current selection:

$ openfoam-selector --query

Most people will find the openfoam-selector-menu more convenient to use.

WARNING: Changes made to the openfoam-selector defaults
will not be visible until you start a new shell!

NOTE: Similar to the behaviour of the mpi-selector, the values registered via the openfoam-selector will not be activated until the next full login. This is to avoid a possible clash of environments when a parallel job still being launched. Of course, you can still simply source the corresponding bashrc file directly. For example,

$ source /usr/lib/openfoam/openfoam2006/etc/bashrc
