-##### openfoam
-
-This is for all simulation experts, which work with [OpenFOAM](https://openfoam.org/) or with the [foam-extend](https://sourceforge.net/projects/foam-extend/) project. It shows the current sourced environment. So, after specifying someting like `alias of5='source /opt/OpenFOAM/OpenFOAM-5.0/etc/bashrc'` (bashrc works also on zsh) in your `.zshrc` and doing `of5` in the terminal, then on the right prompt it will show "OF:" (for OpenFOAM) or "F-X:" (for foam-extend) with its corresponding version number behind it. To activate this segment just use it with: `openfoam` as normal.
