Fluid simulator

System structure

This program uses C++ as the main computational backend, python as a scripting language, and javascript / react as a frontend visualation tool. The C++ code compiles to a shared library which python accesses using ctypes library. The resulting data is sent via WebSocket using Ably to the JavaScript frontend.

Fluid simulation algorithms

The fluid is modelled using smooth particle hydrodyanamics (SPH) as a collection of particles in a 2D grid which seek to repel each other. The relative densities of the particles are calculated, and a subsequent pressure force is exerted on each particle. Boundaries are treated elastically.

To install and run

• Ensure gcc is installed
• Create a virtual environment named 'venv' and run bash // create and enter venv called venv pip install ably, ctypes bash run.sh
