## What it is
Jet is a C++11 fluid simulation engine SDK for computer graphics, created alongside the book 'Fluid Engine Development'. It provides SPH, PCISPH, PIC/FLIP/APIC, smoke, and level-set liquid solvers in both 2D and 3D, with a Python API for prototyping.

## Use cases
- simulate fluids for game or film animation
- learn how fluid simulation engines work
- prototype SPH or FLIP fluid solvers in Python
- add smoke and liquid effects to a graphics application
- study computational fluid dynamics solvers for graphics

## When to choose
- you need a readable, educational fluid simulation engine in C++ or Python
- you want 2D and 3D particle and grid-based solvers out of the box
- you are following the Fluid Engine Development book

## When to avoid
- you need production-grade, actively developed simulation for a commercial pipeline
- you need engineering-grade CFD rather than visual effects simulation
- you need GPU-accelerated real-time simulation

## Facets
- artifact type: library
- maturity: maintenance
- function: simulation, graphics, math, sdk
- domain: computer-vision, graphics, simulation, education
- platform: cpp, python, cross-platform, windows
- tags: fluid-simulation, computational-fluid-dynamics, sph, level-set, physics-animation, c-plus-plus, game-development, macos, linux
