Aim of 2DTissue: Simulating the weather of the world tissue

This physics engine 2DTissue was developed to simulate the collective behaviour of active (self-propelled) particles on arbitrary curved closed surfaces.

How to compile the C++ code

Simply run make in your terminal in the root of this project and everything will get installed and compiled.

How to run the simulation

./build/main --step-count 50 --particle-count 100 --step-time 0.02 --kafka

or if you need help:

./build/main --help

Format the code

CppCheck will help you catch errors and bugs in your C++ code through static analysis.

Navigate into the src folder and run the following command:

cppcheck --enable=all --inconclusive --force --suppress=missingIncludeSystem ./simulation

and

find . -type f \( -name "*.cpp" -o -name "*.h" \) ! -name "argparse.hpp" -exec clang-format -i {} \;

Theoretical Model

The model described is a Vicsek type model (Vicsek et al. 1995, Physical review letters 75(6): 1226) of spherical active particles with a fixed radius confined to the surface of an ellipsoid. Particle interactions are modelled through forces between neighbouring particles that tend to align their velocities (adapted from Szabo et al. 2006, Physical Review E 74(6): 061908).
