A 2D Fluid simulation project

CSC417 Final Project

This is the README for CSC417: Physics-Based Animation, final project. The video associated with this submission is located here: https://youtu.be/RHVkoMmS28c

Description

This project covers Fluid Simulation using 2D SPH.

• Low Viscosity, Single Stream
• High Viscosity, Single Stream
• Low Viscosity, Multi Stream
• High Viscosity, Multi Stream
• Low Viscosity, Dam
• High Viscosity, Dam

Getting Started

Dependencies

• Describe any prerequisites, libraries, OS version, etc., needed before installing program.
• Prerequisites: Tested on macOS mojave
• Python: 3.6.10
• numpy >= 1.19.2
• matplotlib >= 3.3.2

Executing program

In 2d_spy.py, there are 2 flags you can tune:

• mu -> float between [0.2 - 5] -> this sets the viscosity (lower = lower viscosity)

• scene -> choices are either 'ss', 'ms', or 'dam', describing a single stream, multistream, or dam break scenario

• To run this program, examples include:

python 2d_sph.py --scene ss --mu 0.25
python 2d_sph.py --scene ms --mu 1.5
python 2d_sph.py --scene dam --mu 0.25

• The output of this file is a ~8 second video with the following naming format:

{mu}_{scene}.mp4

Example input and output:

python 2d_sph.py --scene ms --mu 0.5 
0.5_ms.mp4

NOTE: Simulation for 500 particles will take about ~ 3 minutes to run and output a video, depending on your workstation. (I.e., don't click on the video output until the python file has output "Video Saved")
