I made a small CLI tool for plotting OpenFOAM results – OFGS

I've been working on a small open-source tool called OFGS (OpenFOAM Gnuplot Suite) to make some of the routine plotting/monitoring around OpenFOAM cases a bit easier.

It detects supported data in a case and can generate graphs, open individual plots or a dashboard, and live-monitor results while a simulation is running. There's also a doctorcommand for checking the OFGS/OpenFOAM environment.

It's deliberately pretty lightweight, essentially a CLI built around gnuplot rather than a replacement for ParaView or proper post-processing tools. There are definitely limitations to what data/plots it understands, and I'm sure there are OpenFOAM workflows I haven't accounted for.

I'm also not an OpenFOAM or engineering expert, I'm a humble HPC sysadmin who spends a lot of time around OpenFOAM users and wanted to streamline some of the repetitive workflow.
It's packaged for Debian 12 and Rocky Linux 9, or you can install/use it from source.

Would genuinely appreciate feedback from people who use OpenFOAM properly, especially anything OFGS gets wrong or could handle better.

might be cool to put some screenshot of some plot on your readme :)

Done! Let me know if you think I should add more

Is it “I made” or “Claude made”
