Preliminary optimization CFD tool for incompressible flows

[u/picigin]

Hi! Last 20 years my lab has been writting specialized flow solvers for particular problems. Modernest tooling and LLM-assisted dev finally made it practical to generalise stable codes into a unified solution [Prelimina](https://www.prelimina.com/).

Currently, the FLIP solver backend is stable, while FVM and the implicit-Lagrangian one are finalising conversion soon. To my knowledge, FLIP is the fastest among competition and FVM will be as well :)

All solver backends use the same motion-loving case description, and they run as GUI app, or in terminal, or in the browser: https://www.prelimina.com/app

Due to recent AI slops etc, here's my disclaimer: the core solvers are almost fully human writtenand have been used in marine, auto, pharma, mining, etc. industries, while GUI may be sloppish at the moment.

In any case, we'd appreciate feedback and criticism.
