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.

With so many things being called Flow these days, this one is probably the most fitting.by LASR

We used sail7 for our sailboat, and this was already open-sourced. https://xflr5.tech/sail7/sail7.htmlby rurban

>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.by tgv
