About this project

A script to create simulation animation of a specific number of double pendulums with a specific error in initial conditions.

Example output

🛠️ Setup/ Preparation

pipenv install --ignore-pipfile --skip-lock --python 3.9
pipenv shell

If faced by UserWarning: Matplotlib is currently using agg, which is a non-GUI backend, so cannot show the figure.

sudo apt-get install python3.9-tk

🚀 Usage examples:

Script options

python double-pendulum.py -h

  -h, --help     show this help message and exit
  -n , --count   Pendulum count
  -d , --delta   Initial condition delta
  -v, --video    Create a video file of the animation
  -t , --time    Number of seconds to simulate

Simulate 5 double pendulums up to 10 seconds with a 0.01 error in the angle initial condition

python double-pendulum.py -n 5 -d 0.01 -t 10

Create an mp4 video file of the case above

python double-pendulum.py -n 5 -d 0.01 -t 10 -v
