Fluid Simulation

Video Demonstration

This project is a fluid simulation implemented in Rust using the Bevy game engine.

• The simulation is based on the concepts presented in this video.
• It achieves approximately 15 frames per second with 100,000 particles, performing 3 physics updates per frame (approximately 45 updates per second) in debug mode.
• The simulation utilizes a maximum of 40-45% of CPU resources (Ryzen 7950X3D).

Key Bottlenecks:

• Bevy's sprite rendering performance.
• Suboptimal multi-threading within the core algorithm.
• Inability to run the simulation in release mode.

Potential Improvements:

• Profiling with the tracey profiling tool to identify performance hotspots.
• Implementing custom mesh rendering for particles to bypass sprite rendering limitations.
