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 a registered Julia package. So to install it,

1. Download Julia (version 1.10 or later). We recommend using JuliaUp so it is easy to change versions in the future.

2. Launch Julia and type

   ```julia julia> using Pkg

   julia> Pkg.add("Subzero") ```

   This installs the latest version that's compatible with your current environment.

3. You are ready to use Subzero! Get started with:

   julia julia> using Subzero
