This project aims to determine the influence of two squirmers on each other.

Objectives

• Understand the "Squirmers" model
• Study the dynamics between two squirmers
• Develop a code to calculate the movement of two squirmers
• Verify if our results align with previous studies

Compilation

To compile the project you need to follow these steps:

python3 -m pip install --upgrade pip
pip install -r requirements.txt
sudo apt-get update
sudo apt-get install ffmpeg

Reproducibility

To run the eight simulations done in the report you need to run:

python3 Code/run.py sim_choice N filename

with N the number of squirmers you want to simulate, sim_choice a parameter used to choose which simulation is done.

sim_choice can be:

• video, a simulation is done with N squirmers and the resulting video is stored in the videos directory
• plot, a simulation is done with N and the resulting graph is stored in the plot directory
• Eo_sim, simulates the behavior of two interacting squirmers close to each other for 9 different Eo parameter and for each Eo, 8 simulations are done with 8 different initial orientation
• border, 4 simulations are done with one squirmer and one border with 4 different initial orientation, the resulting graph is stored in the graphs/border directory
• vicsek, a simulation with N particles is done with 5 time-step the 6 resulting graphs are stored in the graphs/vicsek directory

filename a name file used with video, plot and border.

You can modify the simulation parameters by editing the file Code/run.py and Code/simulation.
