OpenFOAM Configuration

The main OpenFOAM settings are located in the parent etc/ directory. Both POSIX (bash, dash,...) and csh shells are supported. To configure OpenFOAM, source either the etc/bashrc or the etc/cshrc file, as appropriate for your shell.

These source the following files in the config.sh/ or config.csh/ directories:

• setup : finalize setup of OpenFOAM environment (called by bashrc,cshrc)
• settings : core settings
• aliases : aliases for interactive shells
• unset : sourced to clear as many OpenFOAM environment settings as possible
• mpi : MPI communications library settings
• paraview : application settings for ParaView
• scotch : application settings for compiling against scotch
• metis : application settings for compiling against metis

The config.*/example directories contain additional example configuration files for the corresponding shell:

• compiler : an example of fine tuning ThirdParty compiler settings
• openmpi : an example of fine tuning openmpi settings for OpenFOAM
• paraview : an example of chaining to the standard config/paraview with a different ParaView_VERSION
• prefs: an example of supplying alternative site-defined settings
