The VIRus Particle SIMulation with collisions (VirPSim) is a tool to simulate the propagation of a contagious disease on colliding particles. Each particle can have four states: vulnerable, infected, immune and dead. The user selects the initial percentage of particles in each state. Additionally, it is possible to modify the probability of transmission during an interaction, the probability of becoming immune while infected, or the average time it takes for an infected particle to die.
VirPSim is designed to be semi user-friendly and flexible, allowing users to easily customize simulation parameter.
The example.ipynb file is a Jupyter Notebook that serves as an example or demonstration of how to use the VirPSim.
To run VirPSim, you will need the following external package:
NumPy libraryMatplotlib libraryPyTorchtqdm
If you want to make videos of the simulation, you have to install ffmpeg.
It is possible to use an NVDIA graphic card to perform the simulation. You have to install CUDA drivers.
