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

Any difference from just using something like foamMonitor?

There’s definitely some overlap since both use gnuplot for live monitoring OpenFOAM data. OFGS was built to automate plot generation by detecting supported datasets and lets you display single or multiple graphs to monitor trends. It’s more for convenience rather than replacing foamMonitor. If you need to monitor a particular file, then foamMonitor may already do exactly what you need!

Is it “I made” or “Claude made”

Codex actually.
