Aquarius

A Fluid Simulator on GPU (CUDA)

This is Candidate 1023011's 3rd year project at the CS department of Oxford.

Algorithms implemented:

• FLIP (Fluid Implicit Particle) advection
• PCISPH (Predicative-Corrective Incompressible Smoothed Particle Hydrodynamics)
• Position Based Fluid
• Jacobi Pressure Solver
• Surface reconstruction with Marching Cubes
• Multiphase Fluid Diffusion

3D FLIP ball-drop simulation. 50^3 grid, 8 particles per cell, mraching cubes

3D FLIP ball-drop simulation. 50^3 grid, 8 particles per cell, marching cubes. Simulation + Rendering at around 20FPS on a GTX 1080 Ti

Multiphase Diffusion	A red ball of fluid droppping into a blue box of fluid, with diffusion

2D semi-Lagrangian. Implemented in the early phases of the project

Dependencies

• GLFW
• GLEW
• glm
• STB image
• Nukclear

The cmake file should be able to handle these automatically.

Credits

The project uses some of the cubemaps from http://www.humus.name as background.
