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