Mavi.jl

Mavi is a Particle Dynamics Engine.

See the code that generated this video here: examples/welcome_video.jl

Its goal is to provide a common structure for implementing particle dynamics simulations, allowing users to use default behaviors or create their own as needed.

Here are some Mavi.jl features:

• Pairwise interactions, such as Lennard-Jones or Harmonic-Truncated potentials.

• Spaces with different geometries, such as rectangular or circular.

• Spaces with different wall types, such as rigid, periodic or dynamic (walls that exert forces on the particles).

• Quantity calculators, such as kinetic and potential energy.

• Experiment system to collect data from simulations.

• Visualization:

  • Real-time rendering of simulations using Makie.

  • Video generation of simulations.

  • Image generation of simulations.

In addition to the core Mavi module, there is a module named Mavi.Rings, which implements active rings — a model used in this paper: "Segregation in Binary Mixture with Differential Contraction among Active Rings" by Teixeira, E., et al (Physical Review Letters, 2025).
