TSBK03 project

This is a SPH fluid simulation as part of a university projeect course.

Thee fluid simulation is parallelized on the GPU using CUDA and visualize using openGl.

SPH

Parameters

The following parameters control the fluid behavior:

• Particle Mass: PARTICLE_MASS
• Rest Density: REST_DENSITY
• Gas Constant: h_GAS_CONSTANT
• Viscosity: h_VISCOSITY
• Smoothing Radius: h_H

These values are adjustable within the code and can be fine-tuned based on desired fluid dynamics.

Compile & Run

Dependencies

• CUDA Toolkit – for CUDA language support, GPU parallelization, and CUDA/OpenGL interoperability
• GLEW – for OpenGL Extension Wrangler Library
• GLFW
• Thrust – for high-performance parallel algorithms (comes with the CUDA Toolkit)
