This is a fluid and particle simulation made in Rust using the Bevy game engine. The theory, math, and step-by-step paper is (soon to be) uploaded for other's to gain the intuition with molecular dynamics they'll need to create a fluid simulation for themselves!
To run the bevy project,
- Install Rust
- Clone the repository:
git clone https://github.com/gulkaran/fluid-simulation.git - Build the project:
cargo run --release
Current Update - Reintroduced gravity and added pressure forces. It's now more representative of a fluid.
Previous Update - Self-correcting constant density to simulate incompressible properties of fluids (bugs with boundaries for now).
Previous Update - 10,000 particle collision optimized using uniform grids (gif capped to 30fps)
There are different branches that correspond to the different stages of the project. For instance, I diverted from the fluid simulation portion of the project early on to gain more insight on how optimized particle simulations work.
The branch collisions-optimized shows off the simulation in a completely different light,
more focused on optimizing elastic particle collisions in 2D using a uniform grid approach
rather than emulating a fluid. This journey was one of experimenting and learning rather
than trying to build a polished product.
