xkykai 2D Rigid Disc Collision Simulation

Modelling 2D gas particles and Brownian Motion for thermodynamic and stastical physics investigations.

Simulation Visualisation

Brownian Motion

Important Notes

There are 2 versions to most scripts: X_SCRIPT.py and X_SCRIPT_PARALLEL.py. X_SCRIPT_PARALLEL.py are multi-core processing enabled. I have written a parallelised version for scripts worth parallelising.

It is recommended to run the scripts from the terminal to ensure the custom progress bar and parallelisation works properly. However, running in iPython works just fine too.

When running scripts in terminal, the code will be blocked when the GUI shows the graph plotted. Close the GUI window after examining the plot to continue running the script.

Installation

Clone this repo into your machine and run numbered scripts to see the features in this simulation.
