The fastest and most memory efficient lattice Boltzmann CFD software, running on all GPUs and CPUs via OpenCL. Free for non-commercial use.

The FLIP Fluids addon is a tool that helps you set up, run, and render high quality liquid fluid effects all within Blender, the free and open source 3D creation suite.

SPlisHSPlasH is an open-source library for the physically-based simulation of fluids.

A Processing/Java library for high performance GPU-Computing (GLSL). Fluid Simulation + SoftBody Dynamics + Optical Flow + Rendering + Image Processing + Particle Systems + Physics +...

A PIC/FLIP fluid simulation based on the methods found in Robert Bridson's "Fluid Simulation for Computer Graphics"

An open-source tribute to the macOS Drift screensaver

A Multi-Scale Model for Simulating Liquid-Fabric Interactions

A framework for Smoothed Particle Hydrodynamics in Python

3D fluid simulation experiments in Rust, using WebGPU-rs (WIP)

2D liquid simulation in WebGL

3D fluid simulation on the in Unity

A ocean using Phillips spectrum in Unity

A dx12 river renderer using wave particles with interactive vortices.

Implementations in Unity of the Ten Minute Physics YouTube channel. Instead of using Unity's built-in physics engine, you will learn how to make your own. This is useful if you want to simulate ropes, cloth, tires, etc. You will also learn how to make fluid simulations and soft body physics.
