Fast and Flexible Sea Ice Dynamics

Subzero.jl is a native Julia discrete-element model (DEM) for exploring fine-scale sea ice dynamics, reimplementing and enhancing MATLAB model SubZero by Manucharyan and Montemuro.

• 🚀 Runs over 35 times faster that original MATLAB model for title simulation!
• 🧩 Modular simulation model makes it easy to customize simulations!
  • Enable and disable physical processes such as fracturing, ridging, and welding
  • Choose algorithms for key processes (or add your own!)

Installation

Subzero is not yet a registered Julia package. So to install it,

1. Download Julia (version 1.9 or later).

2. Launch Julia and enter into the package manager mode by typing ] in the terminal.

3. Run the following

pkg> add "git@github.com:Caltech-OCTO/Subzero.jl.git"

This will add the package to your package manager. After that you return to the REPL mode by hitting the backspace and you are ready to use Subzero!
