Simulation of the Belousov-Zhabotinski reaction with ASCII characters
The python package you never knew you needed! Now you can appreciate all the glory of the Belousov-Zhabotinsky reaction from the comfort of your console window in a state of the art ASCII art rendering. Your life will never be the same!
This a little python script I made for a class sometime ago. You can play around with the equations coefficients and rendering parameters with command line arguments (see usage). Besides the BZ equation there's also the FitzHugh-Nagumo (for Turing patterns), Gray-Scoot and Cahn-Hilard (simulates phase separation) equations.
The Belousov-Zhabotinsky reaction is the classical examples of non-linear/oscillatory dynamics in chemical systems. The equations that describe the process are reaction-diffusion equations:
Numerally you iterate the equations in a 2D grid. The Laplace operator in a discrete grid is simply a convolution.

Inspired by the following blog posts:
Should work in any python3 version
Needs numpy and scipy
See piplock file
You can pip install the python module with the following command
pip install --user belousov-zhabotinsky
$ python -m belousov-zhabotinsky
Check cli options with:
$ belousov-zhabotinsky --help
You can exit the program by pressing any key
- Gray-Scott mode requires a terminal size bigger than 100x100 to work properly
- There's a plot.py script thay can be use to plot the system in matplotlib.
$ python -m belousov-zhabotinsky.plot
- Fix Gray-Scott
- Make it faster
