Context from the homepage (https://flow5.tech):
An analysis tool for planes and sails operating at low Reynolds numbers
flow5 is a potential flow solver with built-in pre- and post processing functionalities. Its purpose is to make preliminary designs of wings, planes, hydrofoils and sails reliable, fast and user-friendly.

Make it work for paper airplanes and you have a nice teaching tool.
>Performance scales with the speed and number of processor threads.
music to my ears. I wish more software had similar rules.
Certain types of (numerical) problems are very parallel in nature. LLMs, for example. But obviously not every problem is. And sometimes a parallel solution isn't the most efficient.
We used sail7 for our sailboat, and this was already open-sourced. https://xflr5.tech/sail7/sail7.html
Curious that this hit the front page.
What kind of projects is this software used for?

From the main project page. So it’s for designing aircraft, mostly.
With so many things being called Flow these days, this one is probably the most fitting.
